Abstract

Various characteristics of cochlear microphonic responses (CM) were measured in the guinea-pig after perfusing scala tympani with KCl solutions. In addition to a decrease of CM magnitude, the nonlinearity and the symmetry of waveform showed typical modifications suggesting, in addition to a depolarization of hair cells, some mechanical alterations.

摘要

在豚鼠的鼓阶灌注氯化钾溶液后，测量了耳蜗微音器电位反应（CM）的各种特征。除了CM幅度降低外，波形的非线性和对称性也呈现出典型的变化，这表明除了毛细胞去极化外，还存在一些机械性改变。
