Dr. Vilayanur Ramachandran, the director of the Center for Brain and Cognition at the University of California, San Diego, recently gave this excellent speech at the TED (Technology, Entertainment, and Design) Conference. In addition to being an engaging speaker, he may also be one of the only scientists I’ve even seen pull off a leather jacket so well. The talk covers phantom limb pain, synesthesia (when people hear color or smell sounds), and the Capgras delusion, which is when brain-damaged people believe their closest friends and family have been replaced with imposters. This rare disorder has an odd interpretation thats Freudian in nature, and…well…you’ll just have to watch the video to find out what it is. Enjoy.
