Auditory potentials recorded from the vertex of humans by a modified averaging technique have very short latencies and are probably generated by brain stem structures located at a considerable distance from the recording point. The evoked waves, which shOW considerable detail and consistency within and across subjects, may be clinically useful in evaluating subcortical function.
