Isopotential (1-muV) cochleograms were obrained from 19 anesthetized rats from electrodes inserted into scala vestibuli and scala tympani of the first turn. The differential electrode technique is suitable for frequencies above 1-2 kc/s in the rat. CM sensitivity in rats as measured with intracochlear electrodes (26 micrometer in diameter) was considerably poorer than in guinea pigs at frequencies below 2 kc/s, but was within 10-14 db at 2 kc/s and above. The shape of the CM input-output functions were similar to those in the guinea pig and chinchilla, except that the intensity level where the CM becomes non-linear is higher in the rat.
从19只麻醉大鼠的第一圈前庭阶和鼓阶插入电极获得了等电位（1微伏）耳蜗电图。差分电极技术适用于大鼠中高于1 - 2千周/秒的频率。用耳蜗内电极（直径26微米）测量时，大鼠在低于2千周/秒的频率下的CM敏感性比豚鼠差得多，但在2千周/秒及以上时在10 - 14分贝以内。CM输入 - 输出函数的形状与豚鼠和毛丝鼠相似，只是大鼠中CM变为非线性的强度水平更高。
