Some controversy still exists as to whether the inner hair cells of the mammalian cochlea respond to the velocity or displacement of the basilar membrane or to a combination of these over their operating frequency range. A comparison between the nonlinear properties of the receptor potentials within inner hair cells of the basal turn of the guinea pig cochlea and the potentials recorded within the scala media of the same animals for stimulus frequencies between 200 and 3,200 Hz provides evidence that these inner hair cells change from velocity sensitivity to displacement sensitivity at about 1,000 Hz. We infer from this that viscosity within the subtectorial space is high enough to preclude mechanical resonance of the freestanding stereocilia of these cells as a frequency-selective mechanism within the mammalian cochlea.
关于哺乳动物耳蜗的内毛细胞在其工作频率范围内是对基底膜的速度或位移做出反应，还是对这些因素的组合做出反应，仍然存在一些争议。对豚鼠耳蜗基底转内毛细胞中感受器电位的非线性特性与同一动物在鼓阶中记录的200至3200赫兹刺激频率下的电位进行比较，结果表明这些内毛细胞在约1000赫兹时从速度敏感性转变为位移敏感性。我们据此推断，盖膜下空间的粘性足够高，足以排除这些细胞独立的静纤毛作为哺乳动物耳蜗内频率选择机制的机械共振。
