MAGIC WITHOUT MAGIC - MEANING OF QUANTUM BRAIN DYNAMICS

A theoretical framework called ''Quantum Brain Dynamics'' to describe long range ordered dynamics of the quantum system of electromagnetic f ield and water dipole field in the brain is proposed as a revival of t he original idea developed by Umezawa in the early 1960s. Based on Ume zawa's world view of quantum field theory, the manifestation of long r ange ordered dynamics is a macroscopic object of quantum origin, and s o it reveals the existence of specific macroscopic objects in the brai n called ''tunneling photon water.'' Tunneling photon water is shown t o manifest several interesting quantum phenomena involving coherent ph oton emission and transmission, and is suggested to play an important role in quantum blain dynamics. The ordered quantum dynamics of such a macroscopic condensate of tunneling photons with nonvanishing effecti ve charge and mass as tunneling photon water is governed by the macros copic Schrodinger equation, and ensures superconducting phenomena in t he brain at body temperature. The meaning of quantum brain dynamics is clearly explained for brain and cognitive scientists who have been co nfused by either (a) the overstatement with misplaced quantum concepts usually given by those not appropriately schooled in physics or (b) t he understatement with textbook quantum concepts given by technical ph ysicists.
