"The tiny (8 mm) brain implant was designed to allow people who have lost the ability to speak to communicate using only their thoughts. The SBCI is wireless and works by reading brainwaves and translating them to words—the motor neuroprosthesis was placed into O'Keefe's brain using techniques that have been used for several years to treat people with strokes... compose messages by thinking of words or actions (such as mouse clicks), which are translated to activity on a computer screen"
