Abstract
Most components of the human brainstem auditory evoked potential (BEP), elicited by monaural clicks are greater on ipsilateral than on contralateral scalp areas. The major BEP component, Wave V, on ipsilateral areas has also a shorter peak-latency. Under binaural vs monaural stimulation all the BEP components duplicate in amplitudes. Proceeding from these results the sublemniscal (cochleo-olivary-trapezoid) origin of all the BEP components is suggested.
