Excitation of cochlear hair cells is believed to be produced by radial deflection of their stereocilia as a result of shear motion between the reticular lamina and the tectorial membrane. The shear motion must depend on the mechanical coupling between the organ of Corti and the tectorial membrane. It is shown that, because longitudinal stiffness of the tectorial membrane, the shear motion must be enhanced as the wavelength decreases toward the cochlear vibration maximum. The resulting sharpening of the vibration maximum agrees with the frequency selectivity found in the inner hair cells and cochlear-nerve afferents.
人们认为，耳蜗毛细胞的兴奋是由其静纤毛的径向偏转产生的，这是网状板和盖膜之间剪切运动的结果。剪切运动必须依赖于柯蒂氏器和盖膜之间的机械耦合。结果表明，由于盖膜的纵向刚度，随着波长朝着耳蜗振动最大值减小，剪切运动必然会增强。由此产生的振动最大值的锐化与在内毛细胞和耳蜗神经传入纤维中发现的频率选择性一致。
