In a nutshell, what Ramachandran does is to discover how the normal brain works by studying individuals with abnormal neurological conditions. Some of the disorders he discusses are: Agnosia, Anosognosia, Autism, Capgras Syndrome, Cotard Syndrome, and Synesthesia. It's not simply Ramachandran rolling out one bizarre disorder after another. He hits the subject matter from every angle - anatomically, evolutionarily, psychologically, and philosophically. A must read!
