Abstract
Triangular wave acoustic stimulation at 200 Hz produced the expected square wave cochlear microphonic at the round window membrane and within the scala media. Intracellular recordings from inner hair cells (IHC) of the first cochlear turn showed a combination waveform having both spike impulse and square wave features. The IHC response suggests a sensitivity of these cells to both the displacement and to the velocity of basilar membrane motion.
摘要
200赫兹的三角波声刺激在圆窗膜和蜗管内产生了预期的方波耳蜗微音器电位。对耳蜗第一圈的内毛细胞（IHC）进行的细胞内记录显示，其复合波形兼具尖峰冲动和方波特征。内毛细胞的反应表明，这些细胞对基底膜运动的位移和速度均敏感。
