The center of our minds: Vilayanur Ramachandran on TED.com

Brain researcher Vilayanur Ramachandran talks about how brain damage can reveal the connection between the internal structures of the brain and the corresponding functions of the mind. He discusses three specific syndromes: phantom limb pain, synesthesia (when people hear color or smell sounds), and the Capgras delusion, when brain-damaged people believe their closest friends and family have been replaced with imposters. (Recorded March 2007 in Monterey, California. Duration: 23:46.)
