Abstract:
Objective To study the neuroelectrophysiological responsibility, mechanism and clinical application of auditory event-related potential (AERP) generated in bilateral auditory centers with ipsilateral and contralateral recordings. Methods 14 normal young adults were served as subjects. AERPs, including the responsibility, latencies, amplitudes and waveforms, were simultaneously recorded on ipsilateral and contralateral vertexes and analyzed. Results The latencies and amplitudes of AERPs did not show significicant difference statislically between ipsilateral and contralateral vertexes recordings. However, the responsibility of AERP recorded on ipsilateral vertex was more satisfied than that on contralateral vertex, which exhibited smoothing waves, discriminative wave peaks and little hetero-wave. Conclusion The origins of AERP in bilateral auditory centers were essentially symmetrical. Nevertheless, the responsibility of AERP recorded on ipsilateral vertex was more satisfied than that on contralateral vertex, which was related to the components of auditory subcortex, transmission of auditory nerve to bilateral centers and the contralateral inhibiting effect of medial olivo-cochlear system. The effects of multi-generation and multi-component of AERPs on the clinical application should be considered.
