Photon Induced Non-local Effects of General Anaesthetics on the Brain
Photons are intrinsically quantum objects and natural long-distance carriers of information in both classical and quantum communications1. Since brain functions involve information and many experiments have shown that quantum entanglement is physically real, we have contemplated from the perspective of our recent hypothesis2 on the possibility of entangling the quantum entities inside the brain with those in an external anaesthetic sample and carried out experiments toward that end. Here we report that applying magnetic pulses to the brain when a general anaesthetic sample was placed in between caused the brain to feel the effect of said anaesthetic for several hours after the treatment as if the test subject had actually inhaled the same. The said effect is consistently reproducible on all four subjects tested. We further found that drinking water exposed to magnetic pulses, laser light, microwave or even flashlight when an anaesthetic sample was placed in between also causes consistently reproducible brain effects in various degrees. We have in addition tested several medications including morphine and obtained consistently reproducible results. Further, through additional experiments we have verified that the said brain effect is the consequence of quantum entanglement between quantum entities inside the brain and those of the chemical substance under study induced by the photons of the magnetic pulses or applied lights. We suggest that the said quantum entities inside the brain are nuclear and/or electron spins and discuss the profound implications of these results
Monte Carlo simulation of quantum Zeno effect in the brain
Environmental decoherence appears to be the biggest obstacle for successful
construction of quantum mind theories. Nevertheless, the quantum physicist
Henry Stapp promoted the view that the mind could utilize quantum Zeno effect
to influence brain dynamics and that the efficacy of such mental efforts would
not be undermined by environmental decoherence of the brain. To address the
physical plausibility of Stapp's claim, we modeled the brain using quantum
tunneling of an electron in a multiple-well structure such as the voltage
sensor in neuronal ion channels and performed Monte Carlo simulations of
quantum Zeno effect exerted by the mind upon the brain in the presence or
absence of environmental decoherence. The simulations unambiguously showed that
the quantum Zeno effect breaks down for timescales greater than the brain
decoherence time. To generalize the Monte Carlo simulation results for any
n-level quantum system, we further analyzed the change of brain entropy due to
the mind probing actions and proved a theorem according to which local
projections cannot decrease the von Neumann entropy of the unconditional brain
density matrix. The latter theorem establishes that Stapp's model is physically
implausible but leaves a door open for future development of quantum mind
theories provided the brain has a decoherence-free subspace.Comment: 20 pages, 4 figures, appears in International Journal of Modern

Consciousness operates beyond the timescale for discerning time intervals: implications for Q-mind theories and analysis of quantum decoherence in brain
This paper presents in details how the subjective time is constructed by the brain cortex via reading packets of information called "time labels", produced by the right basal ganglia that act as brain timekeeper. Psychophysiological experiments have measured the subjective "time quanta" to be 40 ms and show that consciousness operates beyond that scale - an important result having profound implications for the Q-mind theory. Although in most current mainstream biophysics research on cognitive processes, the brain is modelled as a neural network obeying classical physics, Penrose (1989, 1997) and others have argued that quantum mechanics may play an essential role, and that successful brain simulations can only be performed with a quantum computer. Tegmark (2000) showed that make-or-break issue for the quantum models of mind is whether the relevant degrees of freedom of the brain can be sufficiently isolated to retain their quantum coherence and tried to settle the issue with detailed calculations of the relevant decoherence rates. He concluded that the mind is classical rather than quantum system, however his reasoning is based on biological inconsistency. Here we present detailed exposition of molecular neurobiology and define the dynamical timescale of cognitive processes linked to consciousness to be 10-15 ps showing that macroscopic quantum coherent phenomena in brain are not ruled out, and even may provide insight in understanding life, information and consciousness
Quantum Brain: A Recurrent Quantum Neural Network Model to Describe Eye Tracking of Moving Targets
A theoretical quantum brain model is proposed using a nonlinear Schroedinger
wave equation. The model proposes that there exists a quantum process that
mediates the collective response of a neural lattice (classical brain). The
model is used to explain eye movements when tracking moving targets. Using a
Recurrent Quantum Neural Network(RQNN) while simulating the quantum brain
model, two very interesting phenomena are observed. First, as eye sensor data
is processed in a classical brain, a wave packet is triggered in the quantum
brain. This wave packet moves like a particle. Second, when the eye tracks a
fixed target, this wave packet moves not in a continuous but rather in a
discrete mode. This result reminds one of the saccadic movements of the eye
consisting of 'jumps' and 'rests'. However, such a saccadic movement is
intertwined with smooth pursuit movements when the eye has to track a dynamic
trajectory. In a sense, this is the first theoretical model explaining the
experimental observation reported concerning eye movements in a static scene
situation. The resulting prediction is found to be very precise and efficient
in comparison to classical objective modeling schemes such as the Kalman
filter.Comment: 7 pages, 7 figures submitted to Physical Review Letter
