摘　　要：In the present study, we investigated the influ.ence of the preceding auditory stimulus on the audi-tory-evoked potential (AEP) of the succeeding stimuli, whenthe human subjects were presented with a pair of auditorystimuli. We found that the evoked potential of the succeedingstimulus was inhibited completely by the preceding stimulus,as the inter-stimulus interval (ISI) was shorter than 150 ms.This influence was dependent on the IS1 of two stimuli, theshorter the ISI the stronger the influence would be. The in-hibitory influence of the preceding stimulus might be causedby the neural refractory effect.In the present study, we investigated the influ-ence of the preceding auditory stimulus on the audi-tory-evoked potential (AEP) of the succeeding stimuli, whenthe human subjects were presented with a pair of auditorystimuli.
