Abstract

The suppression of transiently evoked otoacoustic emissions by contralateral sound stimulation is thought to occur as a result of the action of the efferent pathway from the superior olivary complex to the cochlea via the medial olivo-cochlear neurons. The purpose of this study was to determine the time taken for this pathway to activate the suppressive mechanism in response to contralateral sound in normal human subjects. The time for onset of suppression was found to be between 7 and 20 ms.

摘要

对侧声音刺激对瞬态诱发耳声发射的抑制作用，被认为是由于从橄榄上复合体经内侧橄榄耳蜗神经元到耳蜗的传出通路的作用所致。本研究的目的是确定在正常人类受试者中，该通路响应于对侧声音激活抑制机制所需的时间。发现抑制开始的时间在7至20毫秒之间。
