The amplitudes of pattern-reversal VEPs in 25 healty volunteers were significantly higher from the dominant eye than the non-dominant eye in right eye dominant subjects. The difference was present over both hemispheres and over the midline. Handedness did not appear to influence the amplitude asymmetry. A similar trend was noted in left eye dominant subjects, but the difference was significant only at O2. The mean latency of the P100 peak was significantly shorter with stimulation of the dominant eye. These amplitude and latency disparities between dominant and non-dominant eyes provide electrophysiological evidence of lateralization in the nervous system.
