Upper trace: Recordings from a monkey implanted with a fully wireless neural recording microsystem, where neural signals exit transcutaneously by the infrared link, and power to the system is delivered via inductive coupling. Lower trace: Raster plots correlating spiking activity relative to timing of the hand grasp movement of another monkey trained to sit in a chair and grasp (in this “hybrid” device the power to the implant was delivered percutaneously).
