[Long-latency auditory evoked potentials in humans exposed to sonic image movement].

Slow cortical auditory potentials have been studied in man during dichotic click train stimulation perceived as a moving sonic image. Higher values of the amplitude of N1 and P2 components were observed as compared to the response to unmoving image. The amplitude of these components gradually increases with changes in the click frequency within a train (from 15 to 60 Hz), the lower border of this band approximately corresponding to the time interval which is necessary for formation of the sonic image.
