This year's Reith Lecturer is Vilayanur S Ramachandran, Director of the Centre for Brain and Cognition. He has lectured widely on art and visual perception of the brain and is Editor-in-chief of the Encyclopaedia of Human Behaviour. Professor Ramachandran's work has concentrated on investigating phenomena such as phantom limbs, anosognosia and anorexia nervosa. In his final Reith Lecture, Professor Ramachandran argues that neuroscience, perhaps more than any other discipline, is capable of transforming man's understanding of himself and his place in the cosmos.
