Is the brain computable?
One fundamental problem is that we do not understand human consciousness. Many in science and artificial intelligence assume that human consciousness is based on information or computations. Several writers have tried to tackle this assumption, most notably the British physicist Roger Penrose, whose controversial theory suggests that consciousness is based upon noncomputable quantum states in some of the tiniest structures in the brain, called microtubules. Other, perhaps less esoteric thinkers, like Duke’s Miguel Nicolelis and Harvard’s Leonid Perlovsky, are beginning to challenge the idea that the brain is computable. These scientists lead their fields in man-machine interfacing and computer science. The assumption of a computable brain allows artificial intelligence researchers to believe they will
