Phantom moves

SOME amputees feel that they can move their “phantom limbs”, and this affects their other body movements in the same way that moving an intact arm does, say scientists working in California and New Zealand. Every child knows that when you attempt to pat your head with one hand and rub your tummy with the other, both movements get distorted. Vilayanur Ramachandran of the University of California at San Diego and Elizabeth Franz of the University of Otago in Dunedin tested similar kinds of movement distortion in an amputee who reported phantom movement, three amputees who experienced no phantom movement, and six able-bodied volunteers. They found no distortion in the amputees who did not experience phantom movement. But in the amputee who did, the phantom arm interfered with movement in the same way as a real one (Nature Neuroscience, vol 1, p 443),
