Quantum biology meets neuroscience! Talk given by Stuart Hameroff to the Redwood Center for Theoretical Neuroscience at UC Berkeley, on January 9, 2013

Abstract
Cognitive decision processes are generally seen as classical Bayesian probabilities, but better suited to quantum mathematics. For example: 1) Psychological conflict, ambiguity and uncertainty can be viewed as (quantum) superposition of multiple possible judgments and beliefs. 2) Measurement (e.g. answering a question, reaching a decision) reduces possibilities to definite states ('constructing reality', 'collapsing the wave function'). 3) Previous questions influence subsequent answers, so sequence affects outcomes ('contextual non-commutativity'). 4) Judgments and choices may deviate from classical logic, suggesting random, or 'non-computable' quantum influences. Can quantum cognition operate in the brain? Do classical brain activities simulate quantum processes? Or have biomolecular quantum devices evolved? In this talk I will discuss how a finer scale, intra-neuronal level of quantum information processing in cytoskeletal microtubules can accumulate, operate upon and integrate quantum information and memory for self-collapse to classical states which regulate axonal firings, controlling behavior.
