Thanks, gore. Quantum mechanical effects in brain function are also modeled clearly, extensively and mathematically in
The Physics of Consciousness (copyright 2000). Walker makes a compelling, scientific case for the manner in which the nonphysical interacts with the physical in the brain. What's fascinating and utterly fundamental, though, is that the nonphysical is built
directly, inextricably into quantum mechanical math, the implications of which have been missed for a full century. These implications are explored by Walker.
The Physics of Consciousness is a fine book.
