Hemispheric amplitude asymmetries in the auditory evoked potential with monaural and binaural stimulation

Abstract

The present experiment examined auditory evoked potentials (AEPs) under three conditions of auditory stimulation: left ear, right ear, and the two ears simultaneously. It was hypothesized that the white-noise stimulus would result in higher amplitude AEPs in the contralateral hemisphere as compared to the ipsilateral. This was confirmed. There were no latency differences in AEPs recorded from over ipsilateral and contralateral hemispheres. The results obtained appear to provide further evidence for the predominance of the contralateral pathways of the auditory system. © 1975, Psychonomic Society, Inc.. All rights reserved.
