Could quantum brain effects explain consciousness?

S.O.T.T: Physicist Roger Penrose, of the University of Oxford, and anesthesiologist Stuart Hameroff, of the University of Arizona, propose that the brain acts as a quantum computer - a computational machine that makes use of quantum mechanical phenomena (like the ability of particles to be in two places at once) to perform complex calculations. In the brain, fibers inside neurons could form the basic units of quantum computation, Penrose and Hameroff explained at the Global Future 2045 International Congress, a futuristic conference held here June 15-16. The idea is appealing, because neuroscience, so far, has no satisfactory explanation for consciousness - the state of being self-aware and having sensory experiences and thoughts. But many scientists are skeptical, citing a lack of experimental evidence for the idea....read more>>>...
