Abstract: An implantable neurological prosthetic device comprises a plurality of electrodes for stimulating the striate cortex, a matrix of normally closed gates connected in one-to-one relationship with said electrodes, and a plurality of radio receivers tuned to predetermined frequencies and constituting at least two distinctive sets, each gate being connected for switching to an open state to energize the respective one of said electrodes by a unique group of at least two of said receivers from respectively different sets thereof. The receivers are themselves energizable by externally located respective transmitters conveniently positioned by a technique in which the transmitter tuned circuit is included as one arm in a bridge circuit balanced for maximum absorption by the respective receiver tuned circuit. This technique is more generally applicable to any implant provided with a tuned circuit.
