The participants, a 51 - year - old woman who retained some movement in her fingers and wrists and a 54 - year - old man who could still move one of his index fingers slightly, are participants in the BrainGate2 trial, which is testing a neural interface system allowing thoughts to control computer cursors, robotic arms and other assistive devices.

A team led by Brown University neuroscientist John Donoghue has implanted sensors in the brains of four quadriplegic patients that connect signals from the motor cortex to output devices, thereby enabling paralyzed patients to move computer cursors, control robotic limbs, and operate wheelchairs.

EEG is less invasive and less expensive than the implanted electrodes, which have previously been used to control robotic arms and computer cursors by thought alone, he says. (newscientist.com)
