I am reading the book The Brain that Changes Itself by Norman Doidge, because I am hoping to change my brain and make myself smarter. In the book, he mentions Capgras’ delusion, a syndrome in which the sufferer thinks a loved one, or several loved ones – mom, dad, the family dog – have been replaced by impostors. Fascinating. This poor man. Ramachandran, the doctor in this clip, is a figure in the book.
