Quantum Cognition and Brain Microtubules
Δημοσιεύτηκε στις 12 Ιουν 2013
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.
