Abstract
Three-channel Lissajous trajectories (3-CLTs) of the binaural interaction components of the auditory brainstem-evoked potentials were recorded from 17 adult subjects in response to rarefaction, condensation and alternating polarity clicks. All 3-CLTs included 3 planar segments (named Bd, Be and Bf) whose latencies, amplitudes, orientations, sizes and shapes were not affected by click polarity. A significant increase was found in the duration of planar segment Be to alternating polarity clicks. This effect may be explained by limitations of spatiotemporal resolution of the method, which did not allow distinction of contributions from temporally overlapping generators participating in binaural processing.
