Electrically evoked auditory brainstem response (EABR) recordings were made from 38 humans implanted with one of three cochlear prostheses, and from 25 cats. Recognizable auditory potentials were identified in 27 of the profoundly deaf implanted subjects. In both cats and humans EABR waveform morphology and magnitude were independent of electrode configuration and paralleled those of the normal acoustic ABR, but with reduced absolute latencies. EABR recordings are highly susceptible to contamination by stimulus artifact and by elicited non-auditory potentials. Latency, morphology, and magnitude criteria are proposed for identification and analysis of EABR components.
