The efferent innervation of guinea pig cochleas was sectioned medially, at the level of the floor of the fourth ventricle, to study the effects of the crossed part of the medial efferent pathway on the compound action potential (CAP) masking phenomenon. Sectioning reduced CAP masking for a masker level varying with the frequency of the masker and the time elapsed between the masker onset and the probe onset. Functional properties of the crossed part of the medial efferent tracts: latency, thresholds and frequency selectivity, could be deduced from these data.
在豚鼠耳蜗传出神经支配的内侧,于第四脑室底部水平进行切断,以研究内侧传出通路交叉部分对复合动作电位(CAP)掩蔽现象的影响。切断后,对于随掩蔽声频率以及掩蔽声起始与探测声起始之间的时间间隔而变化的掩蔽声强度,CAP掩蔽作用减弱。内侧传出神经束交叉部分的功能特性,如潜伏期、阈值和频率选择性,可从这些数据中推导得出。
