Quantum Consciousness

What is a human being? What is life? Can science give us reliable answers to such questions? The electricity of life. The meaning of human consciousness. Are we alone? Are the traditional contests between science and religion still relevant? Does the word "spirit" still hold meaning today?

Orchestrated Objective Reduction of Quantum Coherence in Brain Microtubules: The "Orch OR" Model for Consciousness
ABSTRACT
Features of consciousness difficult to understand in terms of conventional neuroscience have evoked application of quantum theory, which describes the fundamental behavior of matter and energy. In this paper we propose that aspects of quantum theory (e.g. quantum coherence) and of a newly proposed physical phenomenon of quantum wave function "self-collapse"(objective reduction: OR -Penrose, 1994) are essential for consciousness, and occur in cytoskeletal microtubules and other structures within each of the brain's neurons. The particular characteristics of microtubules suitable for quantum effects include their crystal-like lattice structure, hollow inner core, organization of cell function and capacity for information processing. We envisage that conformational states of microtubule subunits (tubulins) are coupled to internal quantum events, and cooperatively interact (compute) with other tubulins. We further assume that macroscopic coherent superposition of quantum-coupled tubulin conformational states occurs throughout significant brain volumes and provides the global binding essential to consciousness. We equate the emergence of the microtubule quantum coherence with pre-conscious processing which grows (for up to 500 milliseconds) until the mass-energy difference among the separated states of tubulins reaches a threshold related to quantum gravity. According to the arguments for OR put forth in Penrose (1994), superpositioned states each have their own space-time geometries. When the degree of coherent mass-energy difference leads to sufficient separation of space-time geometry, the system must choose and decay (reduce, collapse) to a single universe state. In this way, a transient superposition of slightly differing space-time geometries persists until an abrupt quantum classical reduction occurs. Unlike the random, "subjective reduction"(SR, or R) of standard quantum theory caused by observation or environmental entanglement, the OR we propose in microtubules is a self-collapse and it results in particular patterns of microtubule-tubulin conformational states that regulate neuronal activities including synaptic functions. Possibilities and probabilities for post-reduction tubulin states are influenced by factors including attachments of microtubule-associated proteins (MAPs) acting as "nodes"which tune and "orchestrate"the quantum oscillations. We thus term the self-tuning OR process in microtubules "orchestrated objective reduction"("B>Orch OR", and calculate an estimate for the number of tubulins (and neurons) whose coherence for relevant time periods (e.g. 500 milliseconds) will elicit Orch OR. In providing a connection among 1) pre-conscious to conscious transition, 2) fundamental space-time notions, 3) non-computability, and 4) binding of various (time scale and spatial) reductions into an instantaneous event ("conscious now", we believe Orch OR in brain microtubules is the most specific and plausible model for consciousness yet proposed.

Microtubules as Quantum Antennas
The basic problem in the quantum theories of consciousness is to understand how the macroscopic quantum coherence in brain is generated. Bose Einstein (BE) condensates and coherent states of photons are probably important and microtubules as well as other linear structures (DNA and proteins) are good candidates for the seats of them. The great problem is how the BE condensates and coherents states associated with different linear structures combine to form macroscopic quantum states and it might well be that New Physics is needed.

1. Coherent photons and gravitons from vacuum currents

T(opological) G(eometro)D(ynamics) might provide this new physics [TGD,antenna]. TGD:eish Universe can be regarded as quantum counterpart of a critical system so that the task is only to identify the mechanism realizing the predicted long range quantum correlations. One of the basic differences between TGD and standard gauge theories is that vacuum gauge fields with nonvanishing vacuum gauge current densities are a generic phenomenon. These c-number currents automatically generate quantum coherent states via their coupling to the quantized boson fields.

2. Massless extremals

The so called massless extremals (ME) might be especially relevant in the case of the microtubules [TGD,antenna]. The induced gauge fields associated with the massless extremals can be regarded as nonlinear waves propagating with light velocity. Hence linear structures are especially promising candidates for the seats of ME:s. Since TGD based spacetime is many-sheeted, the spacetime sheet at which the vacuum current flows need not correspond to the spacetime sheets containing the ordinary matter. An important difference as compared to the models of microtubule as quantum wave cavity [Jibu] is that only the source of the coherent light is located to the spacetime region defined by the microtubule whereas the coherent light itself can exist in much larger region. In this manner one avoids the basic problem of the quantum cavity models (by Uncertainty Principle the typical wave length of the coherent light should be determined by the transverse size of the microtubule and should be in UV region).

ME:s and generate both gravitonic and photonic condensates. If the photonic coherent state is present, microtubule can be said to be active, otherwise dormant. The em current associated with ME:s generates a coherent state of photons and microtubule acts as a quantum antenna: inverse wave lengths are integer multiples of the microtubule length so that the longest microtubules generate infrared light.



Fig. 1. Quantum antenna hypothesis


3. How macroscopic quantum coherence is generated?

The basic problem is how microtubules in ME mode can tune the phases and frequencies of their em currents so that individual microtubular coherent states interfere constructively. The gap junctions connecting cells together (in particular, the coherently firing neuron groups), could be crucial factor in establishing the coherence. The fact that axonal microtubules tend to be parallel helps to establish the coherence. Also the classical sourceless Kähler field at the condensate level at which microtubules are condensed, can serve as a pacemaker both in the active and dormant ME modes. Furthermore, the oscillations of the wormhole BE condensate explaining EEG and nerve pulse could be crucial for the establishment of quantum coherence.

The generation of macroscopic quantum coherence could be understood also as self-organization a la TGD. This means that quantum jump takes the role of the basic iterative step, which seems to be essential for self organization and generation of fractals. Laser light and systems consisting of Josephson junctions are known to be self-organizing. The generation of coherent oscillations in quantum entanglement would make possible simultaneous maximum of quantum entanglement for cell groups so that strong form of NMP would allow the cell group to make a quantum jump as a single subsystem.

4. Coherent light and microtubular vision

Since microtubule conformational dynamics (with time scale of order E-10 seconds) is slow as compared with the frequencies of the coherent light, it might provide the means for amplitude modulated transmissions. Brain as a neuron society metaphor suggests that coherent light could for brain what radio waves are for us, or even more since quantum coherence is involved! Microtubules could give rise to an elementary sense of vision for cells in infrared region and there is some empirical evidence for this [Albrecht-Buehler]. This hypothesis explains also Cambrian explosion, which led to the evolution of the multicellular life, as a consequence of the visual consciousness and communication made possible by the microtubules. Vision could correspond quite generally to coherent light in the sense that conscious visual experience is associated with the coherent light sent and received by the neuronal microtubules. The length scale distribution associated with the microtubules in human eye is in the region of the wavelengths of the visible light. In a separate abstract a general TGD inspired identification of the quantum correlates of sensory qualia is considered.

5. Connection with Penrose-Hameroff theory

The quantum superpositions of ME conformations entangled with the corresponding coherent states of photons and gravitons provide a possible realization for 'thinking systems'. Gravitons could indeed be important; after all, gravitation transforms the pure gauge degeneracy of the Kähler action to the genuinely physical spin glass degeneracy. The vacuum degeneracy of Kähler action leads to Penrose Hameroff type picture [Hameroff-Penrose] in which one must consider, instead of a unique quantum average spacetime, a quantum superposition of several of them defined as the absolute minima of the effective action. The p-adicity of the effective spacetime topology, strongly suggested by the spin glass analogy, implies automatically this kind of degeneracy, since p-adic partial differential equations possess a characteristic nondeterminism. Thoughts could be realized as conscious experiences associated with the quantum jumps removing the ME-BE entanglement and would select one of the superposed effective spacetimes (say, the time developments for microtubular conformations).



Fig. 2. 'Association sequence': a geometric model for thought as a sequence of 3-surfaces with timelike separations.

6. Tests and evidence

A possible test for the scenario is the detection of the coherent light emitted by the microtubules. Since no massless charged particles exist, the lightlikeness of the vacuum current generating this light could serve as a unique signature of the phenomenon and the detection of the effect would provide a direct support for TGD. Also laser light at microtubular frequencies could have nontrivial effects on microtubules. Biophotons [Popp] could have an identification as a coherent light generated by DNA acting as quantum antennas. Comorosan effect [Comorosan1,Comorosan2,worm] and less well established phantom DNA effect [worm] having an explanation in terms of coherent light and wormhole BE condensate are should make the testing of the hypothesis possible.

So microtubules do this ?

Image

:D Above is experimental evidence that we have a system of meridians. Those are a 3D structure and acting like a exoskelet and endoskelet. On the meridians physical forces and consciousness are interacting with each other. A well trained consciousness (not brain) is able to interact with physical forces in an amazing way. The antenna or better the interface are the meridians and not microtubules. I dont need another gavitational balck hole in my brain. :lol:

CYTOSKELETON OF THE CELL:
CELLULAR COMPONENTS FOR TENSEGRITY:

DISCONTINUOUS COMPRESSION MEMBER/ MICROTUBULES – 22nm:
Microtubules act as struts in the structure of the cell, or compression members. They extend outward from the nucleus. They are made from the protein tubulin with MAP’s. Organelles are attached to the microtubules and are shuttled along by motor proteins found on the tubules. Specialized organelles made of microtubels are the spindle apparatus that aligns and guides DNA during cell division. They also form cilia and flagella. Microtubules have the ability to assemble and disassemble spontaneously based on stress or strain. this has a direct influence on the instructions to DNA and cell replication and also mRNA and protein synthesis.

CONTINUAL TENSION MEMBER/ MICROFILAMENTS – 6nm:
Microfilaments act as cables that pull the cell membrane inwards. They line the inner surface of the cell membrane. They are made from actin filaments. They control cell movement such as that seen in lukocytes, fibroblast, and skin cells (amoeboid movement) by controlling the gel – sol formation of the cytoplasm. They are the structural rods of microvilli in the intestine. Their contractile properties are well known in skeletal muscle cells. They contract to separate the center of dividing cells. They have the ability to assemble and disassemble spontaneously based on the stress/strain patterns on the cell. This has a direct influence on the instructions to DNA and cell replication and also mRNA and protein synthesis.

INTEGRATORS / INTERMEDIATE FILAMENTS - 7 –11 nm:
Intermediate filaments resemble woven rope and connect microtubules to microfilaments, which makes them known as the great integrators. They are different types of intermediate filaments made of various proteins that appear as irregular threadlike molecules. They are tailored to suit their structural or tension bearing role in specific cell types. They play a central role in structural integrity and resist mechanical stresses applied externally from the cell. They also act to stiffen the nucleus and hold it in place. They resist pulling forces and are the most permanent of the components mentioned so far. They will not assemble or disassemble in a spontaneous pool like microtubules or microfilaments.

THE MICROTRABECULAR LATTICE - < 2nm:
Exceedingly fine interlinked filaments that appears to suspend the microtubules and microfilaments as well as organelles. Some biologist therefore believe it to be not a separate structure but the intricate interconnections between the other three structural components. It is attached to the inner surface of the plasma membrane and acts as the cell’s skeleton. It also plays a role in the organization of cytosol reactions such as glycolysis. Infact enzymes are imbedded in the lattice in some sort of sequential alignment. Ribosomes collect at intersections allowing controlled delivery of cytosol proteins. It is not a static structure and reorganizes according to expansion, contraction and deformation. This structure seems to hardwire the cytoplasm to the nucleus with the specific organelles and the cell membrane. It also has a direct role in the genetic decisions of the nucleus.

GEODESIC FRAMEWORK OF THE CYTOSKELETON:
Triangular, octahedral and tetrahedral forms are self organizing patterns in all biological structures for they represent the best organization of least energy (energy efficient) and mass (size) through structures of continuous tension and local compression, that is through tensegrity. The geodesic dome structure found within the cytoskeleton is a classic example of a recurrent pattern that is found everywhere in nature. Tensegrity structures that are coupled together act as a single structure and will transmitt tension as a coupled tuned response. This means that our bodies vibrate at a molecular level and areas of increased tension or compression resonate as discord in what is intended to be a symphony of tuned responses. In terms of electronic circuits this ability for two separate circuits to resonate at one harmonic frequency is called a “tuned - coupled harmonic oscillator”. Many biolgical structures are tuned this way such as DNA, RNA, proteins, organs, fascia, in fact all levels of connective tissue. The fact that bone acts like so many tiny diodes (semi-conductors) is an example of electro-magnetic fields related solely to tension and compression that organize structure and remodeling of bone and cellular activity (Wolf’s Law). The tension provided by micofilaments pulling inward to wards the cell nucleus causes microfilaments, microtubuels and intermediate filaments combined with the microtrabecular lattice to self organize as a geodesic dome structure.

Where and how in the brain can quantum effects occur? Warm, wet and noisy, the brain at first glance seems a hostile environment for delicate quantum phenomena which generally demand isolation and cold stillness (superconductors), or energy pumping of crystals (lasers). Nonetheless, various authors have implicated ion channels, ions themselves, DNA, pre-synaptic grids and cytoskeletal microtubules as somehow mediating "standard"quantum effects. In a dualist context, Beck and Eccles (1992) proposed that an external "conscious self"might influence the apparently random quantum effects acting on neurotransmitter release at the pre-synaptic grid within each neural axon. Stapp (1993) has suggested that (SR) wave function collapse in neurons is closely related to consciousness in the brain. In our view, cytoskeleta microtubules are the most likely sites for quantum coherence, OR and consciousness.

http://www.quantumconsciousness.org/pen ... rchOR.html
This quote while directed at the human body, is a point that quantum superposition may be possible without supercold superconductors or pumped lasers. I have had a notion for two weeks now that the universe is in a quantum coherent state. I almost thought I might be wrong because the EU is not a superconductor, but then I realized and was assisted via steven that of course scalar time reversed EM is entangled no matter what the quantum state. I think that those states are not mutally exclusive, rather two expressions of the same thing. Therefore it is a safe assumption that the EU is quantum coherent.

Traditionally viewed as the cell’s "bone-like"scaffolding, microtubules and other cytoskeletal structures also appear to fill communicative and information processing roles. Theoretical models suggest how conformational states of tubulins within microtubule lattices can interact with neighboring tubulins to represent, propagate and process information as in molecular-level "cellular automata"computing systems (e.g. Hameroff and Watt, 1982; Rasmussen et al, 1990; Hameroff et al, 1992).

In this paper, we present a model linking microtubules to consciousness using quantum theory as viewed in a particular "realistic"way, as described in Shadows of the Mind (Penrose, 1994). In our model, quantum coherence emerges, and is isolated, in brain microtubules until the differences in mass-energy distribution among superpositioned tubulin states reaches a threshold related to quantum gravity. The resultant self-collapse (OR), irreversible in time, creates an instantaneous "now"event. Sequences of such events create a flow of time, and consciousness.

We envisage that attachments of MAPs on microtubules "tune"quantum oscillations, and "orchestrate"possible collapse outcomes. Thus we term the particular OR occurring in MAP-connected microtubules, and relevant to consciousness, as "orchestrated objective reduction"(Orch OR).

COLLAPSE OF THE WAVE FUNCTION
The boundary between the microscopic, quantum world and the macroscopic, classical world remains enigmatic. Behavior of wave-like, quantum-level objects can be satisfactorily described in terms of a deterministic, unitarily evolving process (e.g. state vector evolving according to the Schrödinger equation) denoted by U. Large-scale (classical) systems seem to obey (different) computable deterministic laws. The transition when system effects are magnified from the small, quantum scale to the large, classical scale (measurement process) chooses a particular "eigenstate"(one state of many possible states). According to the conventional Copenhagen interpretation of quantum theory, the "choice"of eigenstate is purely random. The non-computable R process is known in various contexts as collapse of the wave function, quantum jump, Heisenberg event and/or state reduction.

Von Neumann, Schrödinger and others in the 1930's supposed that quantum collapse, or R effectively occurred when a quantum system interacted with its environment, was otherwise "measured"or consciously observed. Exactly why and how collapse occurs, and how eigenstates are determined, are unknown and indicate a gap in physics knowledge: R is not taken to be an objectively real, independent phenomenon in the standard Copenhagen interpretation. A number of physicists have argued in support of specific models (or of general schemes) in which the rules of standard U-quantum mechanics are modified by the inclusion of some additional procedure according to which R does become an objectively real process. The relevant procedure of any such specific scheme is here denoted by OR (objective reduction). In Shadows of the Mind, Penrose (1994) describes OR in which quantum coherence grows until it reaches a critical threshold related to quantum gravity, and then abruptly self-collapses. Other schemes for OR include those due to Pearle (1989), and to Ghirardi et al (1986), and those which are based on gravitational effects, such as Károlházy et al (1986), Diósi (1989), Ghirardi et al (1990), and also Penrose (1989). Recent work (Pearle and Squires, 1994) lends some considerable support, on general and observational grounds, for a gravitational OR scheme. There are also strong arguments from other directions (Penrose, 1987;1989) supporting a belief that the appropriate union of general relativity with quantum mechanics will lead to a significant change in the latter theory (as well as in the former -which is generally accepted). There is also some tentative, but direct, evidence in favor of this union being a non-computable theory (e.g. Geroch and Hartle 1986; Deutsch unpublished; cf. Penrose, 1994). OR in microtubules relevant to consciousness was first considered in somewhat general terms in Shadows of the Mind. Here we shall adopt a fairly specific proposal for OR (in accordance with Penrose, 1994; Diósi, 1989; Ghirardi et al 1990) applied quantitatively in microtubules in which emergence of quantum coherence U and subsequent OR are "guided"and "tuned"("orchestrated" by connecting MAPs. We thus elaborate a model of "orchestrated OR"(Orch OR) in microtubules which may support consciousness.

An important feature of OR (and Orch OR) is that non-computable aspects arise only when the quantum system becomes large enough that its state undergoes self-collapse, rather than its state collapsing because its growth forces entanglement with its environment. Because of the random nature of environment, the OR action resulting from growth-induced entanglement would be indistinguishable from the random SR, or R process of standard quantum theory.

Consciousness, it is argued, requires non-computability (Penrose, 1989; 1994). In standard quantum theory there is no non-computable activity, the R process being totally random. The only readily available apparent source of non-computability is OR (and Orch OR) self-collapse. An essential feature of consciousness might then be a large-scale quantum-coherent state maintained for a considerable time. OR (Orch OR) then takes place because of a sufficient mass displacement in this state, so that it indulges in a self-collapse which somehow influences or controls brain function. Microtubules seem to provide easily the most promising place for these requirements.

MICROTUBULES AND THE CYTOSKELETON
Ideal properties for quantum brain structures relevant to consciousness might include: 1) high prevalence, 2) functional importance (for example regulating neural connectivity and synaptic function), 3) periodic, crystal-like structure with long-range order, 4) ability to be transiently isolated from external interaction/observation, 5) functionally coupled to quantum-level events, and 6) suitable for information processing. Membranes, membrane proteins, synapses, DNA and other candidates have some, but not all, of these characteristics. Cytoskeletal microtubules do appear to have the requisite properties.

Interiors of living eukaryotic cells (including the brain's neurons and glia) are organized by integrated networks of protein polymers called the cytoskeleton (e.g. Dustin, 1984; Hameroff, 1987). In addition to "bone-like" support, these dynamic self-organizing networks appear also to play roles as each cell's circulatory and nervous systems

The cytoskeleton consists of microtubules (MTs), actin filaments, intermediate (neuro)filaments and microtubule-associated-proteins (MAPs) which, among other duties, link these parallel structures into networks (Figures 1 and 2).

The most prominent cytoskeletal component, MTs are hollow cylinders 25 nanometers (nm = 10-9 meter) in diameter whose lengths vary and may be quite long within some nerve axons. MT cylinder walls are comprised of 13 longitudinal protofilaments which are each a series of subunit proteins known as tubulin (Figure 3). Each tubulin subunit is a polar, 8 nm dimer which consists of two slightly different classes of 4 nm, 55,000 dalton monomers known as alpha and beta tubulin. The tubulin dimer subunits within MTs are arranged in a hexagonal lattice which is slightly twisted, resulting in differing neighbor relationships among each subunit and its six nearest neighbors, and helical pathways which repeat every 3, 5 and 8 rows.

MTs, as well as their individual tubulins, have dipoles with negative charges localized toward alpha monomers (DeBrabander, 1982). Thus MTs are "electrets" oriented assemblies of dipoles which are predicted to have piezoelectric (Athenstaedt, 1974; Mascarenhas, 1974) and ferroelectric (Tuszynski et al, 1995) properties. Biochemical energy is provided to the cytoskeleton in at least two ways: tubulin bound GTP is hydrolyzed to GDP in MTs, and MAPs are phosphorylated. Each tubulin has a large hydrophobic region (Andreu, 1986), a non-polar pocket of amino acid side groups which interact by van der Waals forces and can support quantum level electron delocalizability (e.g. Louria and Hameroff, this Volume).

MTs self-assemble and disassemble (e.g. Kirschner and Mitchison, 1986). The different scaffoldings they assume by their assembly and MAP attachments determine cell form and function including synaptic connections in neurons. Cell architecture (and synaptic connections) can quickly adapt by MT disassembly, and subsequent reassembly and MAP network formation in another shape or direction. Many organized cytoskeletal functions are carried out by MAPs. Some MAPs (dynein, kinesin) act as motors and carry material along microtubules (axoplasmic transport).

Several types of studies suggest cytoskeletal involvement in cognition. For example long term potentiation (LTP) is a form of synaptic plasticity that serves as a model for learning and memory in mammalian hippocampal cortex. LTP requires MAP-2, a dendrite-specific, MT-crosslinking MAP which is dephosphorylated as a result of synaptic membrane receptor activation (e.g. Halpain and Greengard, 1990). In cat visual cortex, MAP-2 is dephosphorylated when visual stimulation occurs (Aoki and Siekevitz, 1985). Auditory Pavlovian conditioning elevates temporal cortex MAP-2 activity in rats (Woolf et al, 1994). Phosphorylation/ dephosphorylation of MAP-2 accounts for a large proportion of brain biochemical energy consumption (e.g. Theurkauf and Vallee, 1983) and is involved in functions which include strengthening specific networks, such as potentiating excitatory synaptic pathways in rat hippocampus (Montoro et al, 1993). The mechanism for regulating synaptic function appears related to rearrangement of MAP-2 connections on MTs (Bigot and Hunt, 1990; Friedrich, 1990).

Other types of evidence also link the cytoskeleton with cognitive function. Production of tubulin and MT activities correlate with peak learning, memory and experience in baby chick brains (Mileusnic et al, 1980). When baby rats first open their eyes, neurons in their visual cortex begin producing vast quantities of tubulin (Cronley-Dillon et al, 1974). In animals whose brains are temporarily deprived of oxygen, the degree of cognitive damage correlates with decrease in measured levels of dendritic MAP-2 (Kudo et al, 1990). Bensimon and Chernat (1991) showed that selective damage of MTs in animal brains by the drug colchicine causes defects in learning and memory which mimic the symptoms of Alzheimer's disease (in which neuronal cytoskeleton entangles). Matsuyama and Jarvik (1989) have linkedAlzheimer's disease to microtubule dysfunction, and Mandelkow et al (1993) and others have pinpointed the axonal MAP "tau protein"as the tangle-causing defect.

How might the cytoskeleton signal and process information? Tubulin can undergo several types of conformational changes (e.g. Engelborghs, 1992; Cianci et al, 1986). Roth and Pihlaja (1977) suggested that patterns of tubulin conformation within MTs represented information. In one example of tubulin conformational change observed in single protofilament chains, one monomer can shift 27 degrees from the dimer's vertical axis (Melki et al, 1989). Whether such mechanical deformation occurs in tubulin within intact MTs is unknown; neighbor tubulins in the MT lattice might be expected to constrain movement. However, cooperativity among tubulins bound loosely in the MT lattice by hydrophobic forces could coordinate conformational changes, and support propagation of wave-like signals in MTs. Vassilev et al (1985) demonstrated signal transmission along tubulin chains formed between excitable membranes. A number of models of signaling and information processing within MTs and other cytoskeletal components have been suggested. These include propagating tubulin conformational changes (Atema, 1974), ion transfer (Cantiello et al, 1991), sequential phosphorylation/dephosphorylation along MT tubulins (Puck and Krystosek, 1992), tensegrity (Wang and Ingber, 1994), non-linear soliton waves along MTs (Chou et al, 1994; Sataric et al, 1992) and "cellular automaton"behavior due to electrostatic dipole coupling among tubulin lattice neighbors (e.g. Rasmussen et al, 1990).

MICROTUBULE INFORMATION PROCESSING
4.1 Protein conformation

Proteins have conformational transitions at many time and size scales (Karplus and McCammon, 1983). For example small side chains move in the picosecond to femtosecond time scale (10-12 to 10-15), but conformational transitions in which proteins move globally and upon which protein function generally depends occur in the nanosecond (10-9 sec) to 10 picosecond (10-11 sec) time scale. Related to cooperative movements of smaller regions, hydrogen bond rearrangements and charge redistributions such as dipole oscillations, these global changes linked to protein function (signal transduction, ion channel opening, enzyme action etc.) may be regulated by a variety of factors including phosphorylation, ATP or GTP hydrolysis, ion fluxes, electric fields, ligand binding, and "allosteric"influences by neighboring protein conformational changes. Noting the extraordinary dielectric strength of proteins (their abilty to sustain a voltage), Fröhlich (1968; 1970; 1975) proposed that the various factors determining protein conformation were integrated through a quantum level dipole oscillation within each protein's hydrophobic region

4.2 Fröhlich's coherent pumped phonons

In addition to linking protein conformation to hydrophobic quantum events, Herbert Fröhlich, an early contributor to the understanding of superconductivity, also predicted quantum coherence in living cells (based on earlier work by Oliver Penrose and Lars Onsager, 1956). Fröhlich theorized that sets of protein dipoles in a common electromagnetic field (e.g. proteins within a polarized membrane, subunits within an electret polymer like microtubules) undergo coherent conformational excitations if energy is supplied. Fröhlich postulated that biochemical and thermal energy from the surrounding "heat bath"provides such energy. Cooperative, organized processes leading to coherent excitations emerged, according to Fröhlich, because of structural coherence of hydrophobic dipoles in a common voltage gradient.

Coherent excitation frequencies on the order of 109 to 1011 Hz (identical to the time domain for functional protein conformational changes, and in the microwave or gigaHz spectral region) were deduced by Fröhlich who termed them acousto-conformational transitions, or coherent (pumped) phonons. Such coherent states are termed Bose-Einstein condensates in quantum physics and have been suggested by Marshall (1989; this Volume) to provide macroscopic quantum states which support the unitary binding of consciousness.

Experimental evidence for Fröhlich-like coherent excitations in biological systems includes observation of gigaHz-range phonons in proteins (Genberg et al, 1991), sharp-resonant non-thermal effects of microwave irradiation on living cells (Grundler and Keilman, 1983), gigaHz induced activation of microtubule pinocytosis in rat brain (Neubauer et al, 1990) and Raman spectroscopy detection of Fröhlich frequency energy (Genzel et al, 1983).

4.3 Cellular automata in microtubules

Computational systems in which complex signaling and patterns emerge from local activities of simple subunits are called cellular automata. Their essential features are: 1) at a given time, each subunit is in one of a finite number of states (usually two for simplicity). 2) The subunits are organized according to a fixed geometry. 3) Each subunit communicates only with neighboring subunits; the size and shape of the neighborhood are the same for all cells. 4) A universal "clock"provides coherence such that each subunit may change to a new state at each "clock tick" 5) Transition rules for changing state depend on each subunit's "present"state and those of its neighbors. Depending on initial conditions (starting patterns), simple neighbor transition rules can lead to complex, dynamic patterns capable of computation. Von Neumann (1966) proved mathematically that cellular automata could function as Turing machines.

In a series of simulations (e.g. Hameroff et al, 1984; Rasmussen et al, 1990) Fröhlich's excitations were used as a clocking mechanism and electrostatic dipole coupling forces as "transition rules"for cellular automata behavior by dynamic conformational states of tubulins within MTs. As in the top of Figure 4, the two monomers of each tubulin dimer are considered to share a mobile electron within a hydrophobic pocket which is oriented either more toward the alpha-monomer (alpha state) or more toward the beta-monomer (beta state) with associated changes in tubulin conformation at each "Fröhlich coherent"time step (e.g. 10-9 to 10-11 sec). The net electrostatic force Fnet from the six surrounding neighbors acting on each tubulin can then be calculated. MT automata patterns can thus represent and process information through each cell; gliders may convey signals which regulate synaptic strengths, represent binding sites for MAPs (and thus neuronal and synaptic connectionist architecture) or material to be transported. Information could become "hardened"in MTs by tubulin modifications or stored in neurofilaments via MAPs.

MT conformational automata patterns provide a further level of computational complexity within each of the brain's neurons. However by considering only classical computing and local neighbor interactions, microtubule automata fail to address the problematic features of consciousness for which quantum theory holds promise.

WAVE FUNCTION SELF-COLLAPSE IN MICROTUBULES: OR AND Orch OR
5.1 The Collapse Criterion and Conscious Thought

Consider a quantum superposition w |A> +z |B> (where w and z are complex numbers) of two macroscopically distinguishable quantum states |A> and |B> . In standard quantum theory and in the absence of environmental entanglement, this superposition would persist forever. If, after a time t, |A> would have evolved to |A>t and |B> would have evolved to |B>t , then w|A> +z|B> must evolve to w|A>t +z|B> t . (This is a feature of the linear nature of U.)

According to the present OR criterion, such macroscopic superpositions are regarded as unstable even without environmental entanglement. Therefore the state w|A> +z|B> will decay in a certain time scale , to either |A> or |B>, with relative probabilities |w|2:|z|2. (This is analogous to the situation with an unstable radioactive particle, with a lifetime and two separate decay modes |A> or |B>, whose branching ratios are |w|2:|z|2.) The idea is that the states |A> and |B> each correspond to clearly defined energy distributions (and to well defined space-time geometries), whereas the combination w |A> +z |B> does not (and so would lead to superpositions of different space time geometries-a particularly awkward situation from the physical point of view!). According to a number of authors (e.g. Diósi, 1989; Ghirardi et al,1986;1990; Penrose, 1993;1994; Pearle, 1992), the gravitational self-energy of the difference between the mass distributions involved in |A> and in |B> will determine spontaneous reduction (at time ) of the superposed combination w |A> +z |B> to either |A> or |B>.

We view |A> and |B> as representing two conformationally coupled quantum states of each tubulin within microtubules, and w |A> +z |B> as the superposition of those states (e.g. Figure 4). We envisage that time T at which the state w |A> +z |B> for each tubulin will decay to either |A> or |B> should relate to the transition between pre-conscious and conscious events.

We assume that pre-and sub-conscious processing corresponds with quantum coherent superposition which can perform "quantum computing"(Penrose, 1989). A number of authors (e.g. Deutsch, 1985; Deutsch and Josza 1992; Feynman 1986; Benioff, 1982) have proposed that quantum coherence can implement multiple computations simultaneously, in parallel, according to quantum linear superposition: the quantum state then "collapses"to a particular result. A state which "self-collapses"(OR) will have an element of non-computability, even though evolution of its quantum coherence had been linear and computable. A quantum superposed state collapsed by external environment or observation (SR, or R) lacks a non-computable element, and would thus be unsuitable for consciousness. Large scale quantum coherence occurring among tubulins (e.g. via electrons in hydrophobic pockets arrayed in the microtubule lattice, or ordered water within hollow MT cores) could take on aspects of a quantum computer in pre-conscious and sub-conscious modes.

We also assume that "non-conscious"autonomic processes correspond with classical, non-quantum computing by microtubule conformational automata. Thus an OR transition from quantum, pre-conscious processing, to classical, non-conscious processing may be closely identified with consciousness itself.

But what is consciousness? According to the principles of OR (Penrose, 1994), superpositioned states each have their own space-time geometries. When the degree of coherent mass-energy difference leads to sufficient separation of space-time geometry, the system must choose and decay (reduce, collapse) to a single universe state, thus preventing "multiple universes"(e.g. Wheeler, 1957). In this way, a transient superposition of slightly differing space-time geometries persists until an abrupt quantum classical reduction occurs and one or the other is chosen. Thus consciousness may involve self-perturbations of space-time geometry.

The extent of space-time superposition causing self-collapse is related to quantum gravity, and equal to one in "absolute units."

Absolute units convert all physical measurement into pure, dimensionless numbers (cf. Penrose, 1994-pp 337-339). This is done by choosing units of length, mass and time so that the following constants take the value of unity:

c(speed of light)=1,
h (Planck's constant divided by 2 pi)=1,
G (Gravitational constant)=1.

Physical quantities relevant to our calculations in absolute units:

second=1.9 x 1043,
nanometer=6.3 x 1025,
mass of nucleon ("dalton"=7.8 x 10-20,
fermi (strong interaction size, diameter of nucleon)=6.3 x 1019.

Using absolute units, we can ask how many tubulins in quantum coherent superposition for how long will self-collapse (Orch OR)?

The gravitational self-energy for a quantum superposition of mass whose displacement for a given time sufficiently perturbs space-time for OR (Orch OR) is taken from the "uncertainty principle"

E=h /T

where h is Planck's constant divided by 2pi , and T is the coherence time.

We estimate T the coherence time from research by Libet (1990) and others (e.g. Deeke et al, 1976; Grey-Walter, 1953; Libet et al, 1979) who found the time scale characteristic of pre-conscious to conscious transitions to be about 500 milliseconds (msec). This is similar to other estimates in the 100-200 msec range (e.g. Koch, this Volume). Hence T=500 msec (half second) seems appropriate from experimental results for at least some functionally significant transitions. Similar calculations may be done using, for example, 25 msec as occurs in coherent 40 Hz excitations.

In absolute units (approximating):

T=500ms=(0.5)1.9 x 1043=1043.

Since h = 1 in absolute units:

E=T-1=10-43.

This is the gravitational self-energy for which nt tubulins displaced in quantum coherent superposition for 500 msec will self-collapse (OR, Orch OR). To determine n/t, we calculate the gravitational displacement self energy E/tfor one tubulin. We assume the tubulin conformational movement displaces its mass by a distance r which is 1/10 the 2 nanometer (nm) radius of the tubulin monomer, or 0.2 nm. In absolute units:

r=0.2(6.3 x 1025)=1025.

Considering tubulin mass as arrays of nucleons, we thus estimate that 5 x 109 tubulins displaced in quantum coherent superposition for 500 msec will self-collapse, Orch OR.

Using the three types of tubulin mass distributions (protein spheres, atoms, nucleons), we obtain 6 x 1013, 109 and 5 x 109 respectively for the required number n(SUB>t of quantum coherent tubulins displaced for 500 msec to elicit Orch OR. Although in approximation all three mass distributions contribute to Orch OR, that which gives the highest energy (fewest tubulins, shortest reduction time if T were not fixed) predominates. Thus, 109 tubulins is perhaps the best estimate. Section 5.3 considers the possible significance of this number of tubulins. As discussed in other papers in this Volume (e.g. Elitzur, Tollaksen), consciousness may be linked to creation of an instantaneous "now" and the flow of time. As Orch OR is instantaneous, non-computable and irreversible, it can provide "now"moments, and directionality in time. Sequential cascades of Orch OR events would then constitute the familiar "stream of consciousness."The Orch OR process in MTs selects patterns (eigenstates of mass distribution) of tubulin conformational states. Figure 7 illustrates eight possible "eigenstates of mass distribution"for Orch OR occurring in 3 adjacent tubulins. The selected patterns can influence neural function by determining MAP attachment sites and setting initial conditions for MT "cellular automata"information processing. These MT activities can then govern intra-neuronal architecture and synaptic function by modulating sensitivity of membrane receptors (in, for example, dendritic spines), ion channels and synaptic vesicle release mechanisms, communication with genetic material, and regulating axoplasmic transport which accounts for delivery of synaptic material components. Microtubule associated proteins (MAPs) attached to certain microtubule tubulin subunits would seem likely to communicate the quantum state to the outside "noisy"random environment, and thereby entangle and collapse it (SR or R, rather thanOR or Orch OR). We therefore presume that these MAP connections are placed along each MT at sites which are (temporarily at least)inactive with regard to quantum-coupled conformational changes. We envisage that these connection points are, in effect, "nodes"for MT quantum oscillations, and thus "orchestrate"the possibilities and probabilities for MT quantum coherence and subsequent Orch OR (Figure 8). MAP connection points can be regularly placed on MT lattices in super-helical patterns (Kim et al, 1986; Burns, 1978) which seems appropriate for their proposed roles as nodes. However in neural MTs, the MAP connection points appear more randomly placed. This would not prevent their acting as "nodes"because the "quantum cellular automaton"activity that we envisage could be extremely complicated, and could well appear to be random. In addition to MAPs, genetic tubulin variability (e.g. Lee et al, 1986), and "learned, experiential" (post-translational) tubulin modifications (e.g. Gilbert and Strochi, 1986) can orchestrate OR. Accordingly, we term the particular objective reduction (OR) occurring in MTs, self-tuned by MAPs and other factors, and relevant to consciousness as "orchestrated objective reduction"(Orch OR).

Because OR phenomena are fundamentally non-local, the coherent superposition phase may exhibit puzzling bidirectional time flow prior to self-collapse (e.g. Aharonov and Vaidman, 1990; Penrose 1989; 1994). As we equate the pre-collapse quantum computing superposition phase to pre-conscious processing, bidirectional time flow could explain the puzzling "backwards time referral"aspects of pre-conscious processing observed by Libet et al (1979).

5.2 How can quantum coherence in microtubules be isolated from environmental entanglement?

When the quantum system under consideration becomes entangled with another system, we must consider the entire state involved. For example |A> might be accompanied by the environment state |P> , and |B> with the environment state |Q> . Then, in place of the state w|A> +z|B> , we have

w|A>| P> + z|B>|Q> .

We must consider mass movement in |P> and |Q> as well as in |A> and |B> , and whenever this dominates, we get, in effect, the random SR, or R process of conventional quantum measurement theory, rather than the non-computable aspects of OR (or Orch OR) that would be important for consciousness.

At first glance, the interiors of living cells would seem unlikely sites for quantum effects. "Noisy"thermal motions of cell water (|P> ) would seem to decohere any quantum coherence and cause random SR, or R collapse. However several factors could serve to isolate microtubules and sustain quantum coherence.

5.2.1 Ordered water

Water on cytoskeletal surfaces can be highly "ordered" extending up to 9 layers (about 3 nm) around each microtubule (Clegg, 1983; Watterson, this Volume). Thermal interactions which would cause decoherence involve energy coupling to oscillations in short range interactions (e.g. hydrogen bonds) among water molecules and groups of water molecules with energy of about kT (10^-12 sec). Interactions of MT surface ordered water molecules with a Fröhlich coherence in MTs are predicted to have a frequency (10^-14 sec) much higher than thermalization energy. Thus MTs may be embedded in "cages"of structured (coherent) water which can act to isolate MT quantum coherence (Jibu et al, 1994). If a quantized electric field generated by Frû…lich pumped phonons in MTs is comparable to the coherent strength of water, the field penetrates/propagates by "piercing"it (self-focusing, filamentary propagation analogous to Meissner effect in superconductivity). Del Giudice et al (1983) showed this self-focussing should result in filamentous energy beams of radius 15 nanometers, precisely the inner diameter of microtubules!

5.2.2 Isolation inside microtubule hollow core

Using quantum field theory, Jibu et al (1994; this Volume) have modeled the ordering of water molecules and the quantized electromagnetic field confined inside hollow microtubule cores. They predict a specific collective dynamics called super-radiance in which each microtubule can transform incoherent, disordered energy (molecular, thermal, or electromagnetic) into coherent photons within its hollow core. The time for super-radiant photon generation is much shorter than the time needed for the environment to act to disorder the coherence thermally.

5.2.3 Sol-gel states

Cytoplasm is comprised of two phases: sol (solution) and gel (gelatinous). Calcium ions binding to actin and other cytoskeletal polymers convert sol to gel transiently and reversibly (e.g. cytomatrix: Satir, 1984). MTs and other MT-associated proteins (i.e.calmodulin) bind/release calcium. Gelatinous phases near adjacent to microtubules could isolate them from thermal effects during quantum coherence.

5.3 The Collapse Fraction

Here we get a very rough idea of the fraction of brain required for Orch OR. In section 5.1 we obtained a very rough estimate that 10^9 tubulins in quantum coherent superposition for 500 msec are sufficient for Orch OR. Yu and Baas (1994) measured about 107 tubulins per neuron. Thus about 100 neurons whose tubulins were totally coherent for 500 msec may be the minimal number for Orch OR, and for consciousness. It may be more likely that only a fraction of tubulins within a given neuron becomes coherent. (Global macroscopic states such as superconductivity can result from quantum coherence among only very small fractions of components.) For example if 1% of tubulins within a given set of neurons were coherent for 500 msec, then 10,000 such neurons would be required to elicit Orch OR. Thus for 500 msec we get a range for minimal consciousness from hundreds to thousands of neurons. Nervous systems of organisms such as the nematode C. elegans contain several hundred neurons. Functional groups of neurons in human cognition are thought to contain thousands. Hebb's (1949) "cell assemblies" Eccles' (1992) "modules,"and Crick and Koch's (1990) "coherent set of neurons"are each estimated to contain some 10,000 neurons which may be widely distributed throughout the brain (Scott, 1995).

Rather than always being 500 msec, time and the number of tubulins may vary, and result in different types of conscious experience. A very intense, sudden input may recruit emergence of quantum coherent tubulins faster so that Orch OR occurs sooner ("heightened"experience, Figure 11c). For example, 1010 coherent tubulins would elicit Orch OR in 50 msec, and so on. Lower intensity input patterns develop coherence more slowly, and Orch OR occurs later. An instantaneous Orch OR may then "bind"various coherent tubulin superpositions whose net displacement energy is T-1, but which may have evolved in separated spatial distributions and over different time scales into an instantaneous event (a "conscious now". Cascades of Orch ORs can then represent our familiar "stream of consciousness."

SUMMARY: ORCHESTRATED OBJECTIVE REDUCTION (Orch OR) OF QUANTUM COHERENCE IN BRAIN MICROTUBULES
The picture we are putting forth involves the following ingredients:

A) A macroscopic state of quantum coherent superposition can exist among tubulin subunits in microtubules across a large proportion of the brain. Plausible candidates for such states include models proposed by:

1) Marshall (1989) in which Frû…lich pumped phonons induce a Bose-Einstein condensate among proteins distributed throughout the brain

2) Jibu et al (1994) in which ordered water within microtubule hollow cores is coupled to Fröhlich excitations of tubulins in microtubule walls

resulting in coherent photons ("super-radiance" 3) Kaivarainen (1995) in which quantum coherent "flickering"clusters of ordered water within hollow microtubule cores are coupled to (non-Fröhlich) tubulin conformational dynamics and generate coherent photons

4) Conrad (e.g. this Volume) in which conformational states and functional capabilities of proteins are controlled by quantum superposition dynamics of electrons and hydrogen bonds within them.

B) The quantum coherent state is weakly coupled to conformational activity taking place in tubulins within microtubules. The link occurs by changes in individual electric dipole moments within tubulins. For example movements of a single electron within a hydrophobic pocket centrally placed within each tubulin dimer may couple to the conformational state of the tubulin (Figure 4).

C) This combined quantum state among many tubulins is able to maintain itself without significant entanglement with its environment for a relevant period of time (up to 500 msec). We envisage several possible mechanisms which could serve to isolate the MT quantum state from its environment within the neuron. These include (see Section 5.2):

Shielding by ordered water on tubulin surfaces
Isolation within hollow MT inner cores
Shielding by gelatinous cytoplasmic layer
D) Cooperative interactions among neighboring tubulins in microtubules can signal and process information by computational mechanisms such as cellular automata behavior. We propose two types of microtubule computation:

Classical computing: conformational patterns propagate through the cytoskeleton to regulate synapses and perform other neural functions (Figure 5). This mode correlates with non-conscious and autonomic activities.
Quantum computing: large scale quantum coherence occurs among tubulins (e.g. via electrons in hydrophobic pockets arrayed in the microtubule lattice) and takes on aspects of a quantum computer (e.g. Deutsch, 1985; Deutsch and Josza 1992; Feynman 1986; Benioff; 1982) where multiple "computations"are performed simultaneously, in parallel, according to quantum linear superposition. We equate quantum computing with pre-and sub-conscious processing.
E) In the quantum computing mode, changes in dimer conformations involve the movement of mass. According to the arguments and criterion described in Section 5.1), we estimate the time scale T , and calculate the number n(sub)t (of coherent superpositioned tubulins) required for self collapse (objective orchestrated reduction: Orch OR) to occur. As we equate quantum computing with pre-conscious processing, we approximate the time scale to be equivalent in some cases to that found by Libet et al (1979) and others (e.g. Deeke et al, 1976; Grey-Walter, 1953) to be characteristic of the transition from pre-conscious to conscious processing (up to 500 msec). For T =500 msec, we get a rough estimate of 109 tubulins required for Orch OR.

F) Microtubule associated proteins (MAPs) attached to certain microtubule tubulin subunits would seem likely to communicate the quantum state to the outside "noisy"random environment, and thereby entangle andcollapse it (SR, or R). We therefore presume that these MAP connections are placed along each MT at sites which are (temporarily at least) inactive with regard to quantum-coupled conformational changes. We envisage that these connection points are, in effect, "nodes"for MT quantum oscillations, and (along with genetic and other tubulin modifications) thus "orchestrate"MT quantum coherence and subsequent OR (Figure 8). Accordingly, we term the particular objective reduction (OR) occurring in MTs and relevant to consciousness as "orchestrated objective reduction"(Orch OR).

G) The Orch OR process selects a new set of tubulin conformational states ("eigenstates of mass distribution" within MTs which can implement and regulate neural function by determining MAP attachment sites and setting initial conditions for "cellular automata"information processing by "classical"conformational transitions. These MT activities can then govern intra-neuronal architecture and synaptic function through modulating sensitivity of membrane receptors, ion channels and synaptic vesicle release mechanisms, communication with genetic material, andregulating axoplasmic transport which accounts for delivery of synaptic material components.

H) How is a particular conformational pattern within each microtubule chosen in the Orch OR process? The Copenhagen quantum interpretation would suggest the selection of states upon (SR, or R) collapse is purely random. Effects of MAPs, genetic and other tubulin modifications can set the possibilities and probabilities ("orchestrate", but reduction within that context is non-computable. As described in Shadows of the Mind (Penrose, 1994), it remains possible that presently unrecognized OR (or Orch OR) quantum-mathematical logic acting on these programming influencesprovides a hidden order.

I) Because OR (and Orch OR) phenomena are fundamentally non-local, the coherent superposition phase may exhibit puzzling bidirectional time flow prior to self-collapse (e.g. Aharonov and Vaidman, 1990; Penrose 1989; 1994). We equate the pre-collapse quantum computing superposition phase to pre-conscious processing. This could explain the puzzling "backwards time referral"aspects of pre-conscious processing observed by Libet et al (1979). (Also see Tollaksen, this Volume.)

J) The persistence and global nature of consciousness is seen as a feature of large scale quantum coherent activity taking place across much of the brain. Varieties of Orch OR with differing coherence times and amounts of coherent tubulin may blend into conscious thought. Very intense, sudden inputs may recruit emergence of quantum coherent tubulins faster than 500 msec so that Orch OR occurs sooner ("heightened"experience, Figure 11c). Lower intensity, unexciting input patterns develop coherence more slowly and Orch OR occurs later. An instantaneous Orch OR may then "bind" disparate tubulin superpositions which may have evolved in separate spatial distributions and over different time scales into an instantaneous conscious "now" Cascades of Orch ORs can then represent our familiar "stream of consciousness."

7 CONCLUSION
Approaches to understanding consciousness which are based on known and experimentally observed neuroscience fail to explain certain critical aspects. These include a unitary sense of binding, non-computational aspects of conscious thinking, difference and transition between pre-conscious and conscious processing, (apparent) non-deterministic free will and the essential nature of our experience. We conclude that aspects of quantum theory (e.g. quantum coherence) and of a newly proposed physical phenomenon of wave function self-collapse (objective reduction, OR, Penrose, 1994) offer possible solutions to each of these problematic features. We further conclude that cytoskeletal microtubules, which regulate intra-neuronal activities and have cylindrical paracrystalline structure, are the best candidates for sites of quantum action and OR, and of "orchestrated OR"(Orch OR). Accordingly, we present a model of consciousness based on the following assumptions:

Coherent excitations (Fr&ounl;hlich pumped phonons) among microtubule subunits (tubulins) support "cellular automaton"information processing in both classical (conformational) and quantum coherent superposition modes. Classical processing correlates with non-conscious, autonomic activity; quantum processing correlates with pre-and sub-conscious activity.

The microtubule quantum coherent computing phase is able to be isolated from environmental interaction and maintain coherence for up to 500 msec (pre-conscious processing).

A critical number of tubulins maintaining coherence within MTs for 500 msec collapses its own wave function (objective reduction: OR). This occurs because the mass-energy difference among the superpositioned states of coherent tubulins critically perturbs space-time geometry. To prevent multiple universes, the system must reduce to a single space-time by choosing eigenstates. The threshold for OR is related to quantum gravity; we calculate it in terms of the number of tubulins coherent for 500 msec to be very roughly 109 tubulins. Larger coherent sets will self-collapse faster, and smaller sets more slowly. Coherent sets which evolve over different time scales and in different brain distributions may be bound in an effectively simultaneous collapse which creates instantaneous "now" Cascades of these events constitute the familiar "stream of consciousness"

.Microtubule associated proteins (MAPs) and other tubulin modifications act as "nodes"to tune microtubule coherence and help to orchestrate collapse. We thus term the specific OR proposed to occur in microtubules and intrinsic to consciousness as "orchestrated objective reduction"(Orch OR).

.The Orch OR process, which introduces non-computability (Penrose, 1989; 1994), results in eigenstate patterns of tubulin conformational states which help direct neural function through the actions of microtubules.

In providing a connection among 1) pre-conscious to conscious transition, 2) fundamental space-time notions, 3) non-computability, and 4) binding of various (time scale and spatial) superpositions into instantaneous "now" we believe Orch OR in MTs is the most specific and plausible model for consciousness yet proposed.

Since we were taking about the electric liquid crystal tensegrity structure and what are emotions and how do they fit in to this system. I found this quote at the Aether Physics Model web page.
"Evidence gathered from the neurosciences show that conductance is a direct measurement of emotions, and conductance is also shown to be a quality of the Aether. Thus there is a physics link to suggest the Aether is involved with certain aspects of mind, if not all aspects of mind."
http://www.16pi2.com/gforce.htm
I thought that was an interesting quote.
I have further study from the same book, Secrets of the Aether, that shows some interesting leads concerning conductance.
"Although the classic physics, shows resistance to be the reciprocal of conductance, experiments do not verify this. But for reasons related to the different measurement principles and the electrical properties of the skin, the hypothesis of linear relationship between changes in the skin conductance and the resulting resistance from the measurement cannot be maintained.

Therefore it is recommended that researchers use skin conductance only.

However there is evidence to suggest a linear relationship between conductance and magnetic flux, it is showing for normal wall thickness, the flux leakage is determined essentially by the wall conductance, defined as the product of wall thickness and wall conductivity. There are other instances, especially in the field of nanotechnology, were conductance has a linear, reciprocal relationship to magnetic flux."
As I learn more about the Aether physics model, I will be able to join the consciousness studies with the Aether physics studies based on conductance and magnetic flux, things we can measure.

Pentagon Explores Quantum Biology

For years, military researchers have been exploring how the seemingly-improbable realm of quantum mechanics could impact information technology -- leading to faster, more powerful computers, next-gen radars and radios, and encryption that's all-but-impossible to break. Now, the Pentagon's blue-sky research arm is starting to look at how quantum mechanics might impact biology, as well.

Darpa's Defense Sciences Office has announced a workshop to discuss "innovative research that will investigate the way that nature may be exploiting quantum mechanical effects in biological systems." And of course, they need an acronym to do it. So get ready for "QuBE," short for "Quantum Effects in Biological Environments."

Scientists have recently discovered that quantum energy transfers allow plants and cynobacteria to convert sunlight into chemical energy nearly instantly, and with almost 100 percent efficiency. "As energy passes between molecules involved in photosynthesis, a newly observed 'wavelike characteristic' allows the energy to 'simultaneously sample all the potential energy pathways and choose the most efficient one,'" our Wired Science co-bloggers observe. They liken it to the "sci-fi trope" in which "a digital consciousness" is split "into several 'forks' that simultaneously explore different courses of action before telling a central consciousness what to do."

Darpa says there are other biological examples of quantum effects -- including an explanation, perhaps, for how birds are able to navigate along the Earth's magnetic fields. The key may be the so-called "quantum Zeno effect," explains the Physics ArXiv Blog.

This is the watched-pot-never-boils effect on the qauntum scale. It states that the act of observing a quantum system can alter its evolution in a way that maintains the state for longer than expected.

One well-known example is that it is possible to slow down the rate at which molecules convert from ortho to para isomers when they are constantly involved in collisions.

[Iannis Kominis at the University of Crete] says a similar thing happens in birds: the presence of a geomagnetic field extends the lifetime of the singlet-triplet mixture from which the ions recombine. This gives the magnetic field time to bias the outcome of the recombination.
