New Scientist Tech - Breaking News - Brain-implant enables mind over matter: "Electrodes implanted in Nagle's brain measure the neural signals generated when he concentrates on trying to move one of his paralysed limbs. Software trained to recognise different patterns of neural activity then translates imagined gestures into the movement of an on-screen cursor or a robotic arm at Nagle's side.

'The fundamental findings are that you can record activity from the brain years after injury, that thinking about movement is sufficient to activate the brain, and that we can decode the signal,' says John Donoghue of Brown University in New York, who led the work."
