Photo of a subject patient in a human clinical pilot trial, operating a cursor on a display screen by direct cortical “thought-to-action” control (after [24], [62] and courtesy of BrainGate2.org). The implanted multielectrode array is connected via a skin penetrating wirebundle to a head-mounted stage for analog signal amplification. This stage is tethered to other signal processing (digital) and neural signal decoding electronics in the subject’s vicinity, and the operation is supervised by trained technical personnel.
