Vilayanur Ramachandran tells us what brain damage can reveal about the connection between celebral tissue and the mind, using three startling delusions as examples.

V.S. Ramachandran is a mesmerizing speaker, able to concretely and simply describe the most complicated inner workings of the brain. His investigations into phantom limb pain, synesthesia and other brain disorders allow him to explore (and begin to answer) the most basic philosophical questions about the nature of self and human consciousness.

Ramachandran is the director of the Center for Brain and Cognition at the University of California, San Diego, and an adjunct professor at the Salk Institute.
