I like to check out TED talks every now and then. They take a viewer to new subjects and new ideas. I found the talk linked above and recognized the presenter as the author of "Phantoms in the Brain", a book that a group of friends discussed about a decade ago.
I get impressed by finding that people who have lost an arm or a leg have complained that the absent arm aches and have been making such complaints since the 1600's. Ramachandran found ways to deal with the situation and help, and to do so at low cost. Sounds impossible at first but it isn't and pursuing the matter shows a bit about how the 3 lb. organ in our heads works.
I think it is surprising that certain patients are deluded about their mother when they see her but not when they talk to her on the phone.
