“Neurolutions, a startup based in St. Louis, is developing a small, implanted device that translates signals recorded from the surface of the brain into computer commands…the device is based on electrocorticography (ECoG), in which a grid of electrodes is surgically placed directly on the surface of the brain to monitor electrical activity…[scientists] are developing a much smaller version that would be implanted long term to allow paralyzed patients to control a computer and perhaps prosthetic limbs and other devices…Tests of more than 20 patients have shown that people can quickly learn to move a cursor on a computer screen using their brain activity.”
