Researchers Identify Phantom Limb Brain Activity

mmmscience writes "Researchers in Switzerland think they had identified the regions of the brain responsible for creating phantom limbs and the senses that go along with them. Scientists studied a stroke victim who claimed that the phantom limb of her now-paralyzed left arm could do a number of things a normal limb could do, including 'scratch an itch on her head, with an actual sense of relief.'"
