It is well known that the auditory evoked N100m response is dominant in the contralateral hemi-sphere to the stimulated ear: N100m latency is shorter and N100m amplitude is larger in the contralateral hemisphere than the ipsilateral hemi-sphere. Interhemispheric asymmetry of the N100m responses were reported in terms of the equivalent dipole localization: the right hemispheric N100m dipole is more anterior to the left hemispheric dipole. In the present study, we investigated inter-hemispheric asymmetry of the auditory evoked P50m and N100m response in terms of signal ampli-tude.
