<unk> s <unk> s) or microelectrode<unk> s are devices that contain multiple plates or shanks through which neural signals are obtained or delivered, essentially serving as neural interfaces that connect neurons to electronic circuitry.  There are two general classes of<unk> s: implantable<unk> s, used in vivo, and non-implantable<unk> s, used in vitro.
