Middle-ear to basilar membrane (BM) velocity transfer functions are reported for seven locations in the hook region of a single cat cochlea. These transfer functions were recorded at high sound pressure levels in a linearized, or passive cochlea, and resemble those reported previously by Wilson and Evans (1983). They demonstrate longitudinal tonotopicity with a gradient of approximately 3.6 mm/octave. When allowances are made for the nonlinear mechanisms previously demonstrated in active hook region preparations (Cooper and Rhode, 1992), the data are also consistent with the tonotopic map derived from the intracellular dye-filling studies of Liberman (1982).
报告了单只猫耳蜗钩状区域七个位置的中耳到基底膜（BM）的速度传递函数。这些传递函数是在一个线性化的或被动的耳蜗中，于高声压水平下记录的，并且与Wilson和Evans（1983年）之前报告的那些相似。它们展示出纵向音调定位，梯度约为3.6毫米/倍频程。当考虑到之前在活跃的钩状区域制备物中所证明的非线性机制时（Cooper和Rhode，1992年），这些数据也与从Liberman（1982年）的细胞内染料填充研究得出的音调定位图一致。
