Intracellular recordings were made from outer hair cells in the third turn of the guinea pig cochlea, and the electrical characteristics of the cells were compared to those of inner hair cells, supporting cells, and extracellular spaces from the same recording region. Outer hair cells have higher membrane potentials than do inner hair cells, but they produce smaller a-c receptor potentials. The frequency response characteristics of both types of hair cells are probably not significantly different. In the frequency region where tuning is optimal, both cell types produce depolarizing d-c receptor potentials, but outer hair cells also generate hyperpolarizing responses at low frequencies.
在豚鼠耳蜗第三圈的外毛细胞上进行细胞内记录，并将这些细胞的电特性与来自同一记录区域的内毛细胞、支持细胞和细胞外间隙的电特性进行比较。外毛细胞的膜电位比内毛细胞高，但它们产生的交流受体电位较小。两种类型毛细胞的频率响应特性可能没有显著差异。在调谐最佳的频率区域，两种类型的细胞都会产生去极化的直流受体电位，但外毛细胞在低频时也会产生超极化反应。
