In his new book, 'The Man Who Wasn't There,' Anil Ananthaswamy examines the ways people think of themselves -- and how those perceptions can be distorted by certain brain conditions. For instance, a patient with Cotard's Syndrome is utterly convinced that they are already dead, and a patient with Body Integrity Identity Disorder perceives that a body part is not their own. Also, rock historian Ed Ward shares blues musician Slim Harpo's story.
