Brain and arm implants help paralyzed US man feed himself

LONDON (AP) — A paralyzed man was able to feed himself for the first time in eight years, after doctors implanted sensors in his brain that sent signals to his arm. After first practicing with virtual reality, Kochevar was then able to drink coffee through a straw and eat forkfuls of mashed potatoes and macaroni and cheese on his own. Similar technology has previously been used to help a few paralyzed people in experimental studies do things like grasp a bottle, hold a toothbrush and move their legs, but the brain and muscle implants haven't been used beyond the laboratory and are not a cure for paralysis. Scientists have mostly focused on decoding brain signals to move robotic limbs; translating brain messages to move the body's own limbs is much more challenging and often results in movement that is a bit jerky and awkward.
