I first read Sir Roger Penrose's The Emperor's New Mind back when I was in college working on my psychology degree. In the book Penrose reviewed much of the current research surrounding consciousness and concluded that the most reasonable explanation for the bulk of the data was to envision consciousness as a coherent phenomenon related to quantum interactions within the brain. At the time of publication, 1989, he concluded that these quantum effects were possibly unknowable, which would seriously impede any effort to construct a fully conscious form of artificial intelligence.
However, since 1989 incredible strides have been made in terms of mapping brain activity. More recently Penrose and others who support his ideas believe they may have found the point of interaction between neurons and the quantum realm, in the form of tiny structures called microtubules. With the recent fuss over Eben Alexander's Proof of Heaven, near-death experiences are once more in the news. On a recent television documentary, Penrose colleague Dr. Stuart Hameroff commented on how the quantum microtubule idea could model and explain such experiences.

According to this idea, consciousness is a program for a quantum computer in the brain which can persist in the universe even after death, explaining the perceptions of those who have near-death experiences.
