Aim: To examine the N1/P2 complex of the auditory evoked potential and its susceptibility to PPI and to compare the amplitudes of these responses and their suppression. Material and Methods: Twenty healthy volunteers, ten males and ten females were entered in this study. Their mean age 21.5 years. Before entering the study their hearing thresholds at 0.5,1,2, and 4k HZ were measured, none of them were found to have thresholds above 20dB. Results: The female subjects in this study showed slightly higher auditory evoked potential responses and lower response latencies than the males. Conclusion: Our findings are consistent with sex differences. These are attributed to differences in skull dimensions, brain volume and conduction distances.
