Mind-controlled prosthetics without brain surgery

University of Maryland researchers have created a mathematical model that relates hand movements to EEG signals (which measure electrical activity of the brain), suggesting that EEG might also be used to control a prosthetic arm.

EEG is less invasive and less expensive than implanted electrodes, which have previously been used to control robotic arms and computer cursors by thought alone.
