Localization of callosal auditory pathways

Abstract

The position of the auditory pathways in the human corpus callosum has not been defined by modern imaging techniques. We report a case with a discrete hemorrhagic lesion in the posterior body of the corpus callosum. The only signs of disturbed callosal function were limited to the auditory system—suppression of left ear stimuli with dichotic listening and neglect of left-sided auditory simultaneous stimuli.
