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.
