	Mind-Quantum role?
		Eccles requires that the options of a single vesicle discharging or not discharging both have non-zero quantum probabilities, so that such neural events are genuinely under-determined by quantum mechanics, and the way is open for them to be determined by the mind.
		Another proposal by Marshall (1989) is that the mental and bodily realms derive directly from a quantum realm, as separate appearances of an underlying structure given by quantum mechanics.
		This therefore requires not only that the brain amplifies quantum indeterminism, but also that long-range and long-time correlations of quantum phases are set up in the brain, by means for example of a structure proposed by Fröhlich.

	Quantum Brain
		In the quantum model of Ricciardi and Umezawa the elementary constituents are not the neurons and the other cells and physiological units, which cannot be considered as quantum objects, but some dynamical variables, called corticons, able to describe stationary or quasi-stationary states of the brain.
		The problem of memory capacity in the quantum brain model, arising from the fact that vacua labelled by different code numbers belonging to the same class are accessible only by a sequence of phase transitions, however, a solution is in the intrinsic dissipative character of brain dynamics.
		Finally, according to the original quantum brain model, the recall process is described as the excitation of dipole wave quanta modes under an external stimulus which is "essentially a replication signal"[9] of the one responsible for memory printing.

	Quantum Consciousness . Stuart Hameroff
		The boundary or edge (quantum state reduction, or ‘collapse of the wave function”) between the quantum and classical worlds somehow involves consciousness.
		Roger’s mechanism for an objective threshold for quantum state reduction connects us to the most basic, “funda-mental” level of the universe at the Planck scale, and is called objective reduction (OR).
		Quantum Mind Archives includes abstracts from the two Quantum Mind conferences held in 1999 in Flagstaff, Arizona, and in 2003 in Tucson.

	Quantum brain dynamics - Wikipedia, the free encyclopedia
		In neuroscience, quantum brain dynamics (QBD) is a proposed theory to explain the function of the brain with quantum mechanics.
		Although there are many blank areas in understanding the brain dynamics and especially how it gives rise to conscious experience it should be noted that quantum mechanics is only believed to be capable of explaining the enigma of consciousness and currently there is no experimental verification.
		Quantum field theory of evanescent photons in brain as quantum theory of consciousness.

	THE QUANTUM BRAIN
		EEG recordings were made from the brains of both subjects synchronized with the stimulus given to one of them.
		These findings indicate that the human brain is capable of establishing relationships with other brains (when it interacts with them appropriately) and sustaining such correlations even at a distance.
		When one subject is stimulated and observes a light flash, consciousness simultaneously collapses the wave function of the correlated partner in identical states as indicated by the similarity of the distinct evoked potential in the stimulated subject to the transferred potential in his or her non-stimulated partner.

	Brain, Chaos, Quantum Mechanics
		The brain may utilize sensitive instability to deal with computationally difficult situations by mapping parallel representations on a fractal basis similar to Penrose's (1989) fractal algorithms for parallel computation (Dewdney 1989), with the added feature that continuous dynamical instability is used in addition to resolve ambiguous situations which remain intractable digitally.
		Such time-reversal is used in the transactional interpretation of quantum mechanics (Cramer 1986) fig 14(c), a mutual encounter between emitter and absorber is modelled by the release of crossed-phase advanced and retarded waves, each having zero-energy, the offer wave of the emitter and the confirmation wave of the absorber.
		The central task of the brain is the representation of the activity of the organism in terms of both past and future temporal dynamics.

	Quantum Consciousness
		Lockwood argued that sensations must be intrinsic attributes of physical states of the brain: in quantum lingo, each observable attribute (e.g., each sensation) corresponds to an observable of the brain.
		Many properties of the brain are the same properties that are commonly associated with holograms: memory is distributed in the brain and memories do not disappear all of a sudden, but slowly fade away.
		Subjective reduction is what happens when an observer measures a quantity in a quantum system: the system is not in any specific state (the system is in a "superposition" of possible states) until it is observed, the observation causes the system to reduce (or "collapse") to a specific state.

		It's hardly a quantum leap (or is it?) to suggest that quantum level "events" - events which have no cause - bear at least a superficial relationship to the ancient Greek and Scholastic notion of God as the "uncaused cause" of matters material.
		Though presumably the amplification of the quantum capacity for experience through a human (or artificial) nervous system would be necessary for the richly textured sense of experience we as humans experience.
		Since scientists are reasonably certain that quantum events are caused by nothing, as if particles "chose" which path to take, some have hoped that evidence of acausal quantum behavior in the brain would open up the possibility of free will and the intrinsic existence of consciousness.

	Quantum Future
		The achievements of quantum physics during this century and its undisputed success and influence are indeed impressive.
		The source of this plethora of interpretations is, perhaps, the fact that "standard" interpretations of quantum theory are not satisfactory and it is becoming increasingly apparent that an alternative physical theory may be needed.
		But, as so many books have been composed of discussions based on experimental, theoretical, or philosophical viewpoints with little reference to their interrelation, it seems appropriate to attempt to obtain a more balanced picture of all the elements which must be taken into account.

		On the other hand, large scale quantum effects have been typically known to happen only in special circumstances (such as low temperature or very high pressure): from this point of view the burden is on the advocates of a quantum brain perspective to show how their view is not unreasonable.
		My view, that evolution is wily, subtle and integrative and likely quantum coherent to the core, was spelled out several years ago in a posting to psyche-d.
		A model of 'top level control' by a quantum state has been discussed by Henry Stapp, who argues generally that the quantum description is appropriate to consciousness in a way the classical one cannot be.

		Therefore, the brain cannot be in a state of change, it must be in one state or another, there is no in between.
		The QBT states that our brain takes in reality one moment at a time, it is never in a state where it is observing something change.
		Quantum mechanics cannot be used to explain the universe as a whole in all venues, however, can explain the movements of an electron, or the actions of a fl hole.

	Doug Renselle's 2002-2003 Review of Jeffrey Satinover's The Quantum Brain
		Quantum nature offers unlimited qubit 'precision,' ('precision' is a classical term which needs quantum/Quantonic English Language Remediation; it assumes 'true' finite element analytic reduction; no such animal 'exists' in quantum reality) which is another way of saying reality's models are real, and to model reality, we must use he~r to model he~rself.
		Quantum (we call it:) comtext is both quantum separable and inseparable, which we may show as quanton(separable_complement,in(non)separable_complement).
		But in quantum reality, due all these miracles, we may not classically know real initial state (i.e., to unlimited qubit 'resolution'), nor classical characteristics (there are no classical characteristics of an object/system in quantum reality), nor interactions (quantons interrelate via coobsfection; they do not 'interact' by classical lisr 'forces').

	Vitiello's Quantum Brain
		The change in the mental pilot wave patterns is a mirror or homomorphic image of the corresponding change in the configuration of the particles and electrical fields of the brain to which the pilot wave is inseparably attached.
		Note, however, that teleportation of quantum states is possible, and this may imply the possibility of transference of qualia between widely separated brains or artificially conscious quantum computing machines.
		He claims that this nonlocal quantum connection or entanglement between the two quanta, one in the Frohlich wave the other in the external environment, "can be seen as a self-interaction term" of the Frohlich mode in which the environmental twin is part of the "self-recognition" process.

	Quantum mind - Wikipedia, the free encyclopedia
		There are many gaps in current understanding of how consciousness arises, to the extent that we are uncertain whether it is strictly from the functioning of the human brain or if awareness involves more of our nervous system and/or other aspects of our totality.
		It could be argued that a strictly classical interpretation of the Physics and Neurobiology involved does not even admit the possibility of free-will, or would assert that it is illusory, and has no clear explanation for the phenomenon of conscious awareness.
		Accordingly; the quantum mind hypothesis claims that only quantum mechanics is capable of explaining conscious experience.
