Electrically Evoked Brain Stem Auditory Potentials

Abstract

University of Melbourne cochlear prostheses were driven to deliver pulse stimuli at a repetition rate of 10 Hz. Brain stem auditory evoked potentials were recorded in the customary way. The magnitude of the presumed wave V was plotted against stimulus amplitude. Also, 10-Hz square waves of current were injected through a promontory needle into totally deaf patients with no implant. In most cases we did not succeed in recording a response, but in one case a wave iii and a wave V were recorded.
