Abstract

A three-dimensional electrode device is disclosed. The device is useful as a neuron interface or as a cortical implant. A plurality of spire-shaped electrodes, formed of semiconductor material, are associated with a rigid base. The electrodes are electrically isolated from each other at the base. Multiplexing circuitry allows the electrodes to be addressed individually.
