Abstract

A simple and effective ground electrode is described for use in human electrophysiological recordings. This electrode consists of a wire clip that holds a silver disc of 1 cm diameter which is clipped to the lower lip of the subject. It is found that this simple ground electrode reduced the background noise and/or stimulus artifact at least as effectively as other conventional grounding techniques. © 1988.
