When your mind disowns a limb

Here's an interesting Scientific American article (I really miss getting that magazine... someone buy me a subscription please):

... what if you could be fooled into thinking that one of your hands belonged to someone else? Scientists at the University of Oxford recently incited this false perception through an illusion—and they found that when people felt dissociated from a limb, their brain devoted less processing power toward that limb and even interfered with its temperature regulation. These findings, building on a smattering of other studies in disembodiment, suggest that the conscious mind’s control over basic body function is much stronger than scientists once thought.

Sounds kind of creepy... but also kind of fun!
