Fusiform gyrus key to understanding neuroanatomic basis of Capgras delusion

Posted Sep 20 2011 7:45pm
Thanks to Doug Shevlin, MD (pictured with crawdaddy ) for steering me toward this TED talk by neuroscientist Vilayanura Ramachandran, MD, PhD . Dr. Ramachandran discusses the neuroanatomical substrate of the Capgras delusion, a neurological deficit about which I have blogged before . Dr. Ramachandran explains that the origin of this fascinating deficit stems from a severing (typically resulting from a stroke or neurodegenerative disorder) of the connection between the fusiform gyrus (the face perception area of the brain) and the amygdala (which gages the emotional significance of a perception). Good stuff....  including the crawdaddy.
