Right-left asymmetries in the human brain stem: auditory evoked potentials.
Right-left asymmetries were found in the amplitudes (but not latencies) of 3 peaks of the brain stem auditory evoked potentials: most consistently in III(+), but also in I(-) and IV(+). In all 3 cases the mean amplitude was significantly larger for right ear stimulation than for left. The similarity between the distribution of cerebral dominance and the asymmetry of peaks III(+) and IV(+) suggests the possibility that cerebral asymmetries for language are related to asymmetries in the brain stem auditory system.
