The suggestion that the frequency dependence of the slope of the cochlear fibre discharge rate vs. intensity function is evidence for a frequency-dependent basilar-membrane nonlinearity, is challenged by a demonstration that such frequency dependence of slope can be derived from a model of the cochlea which involves only linear filters and memoryless, frequency-independent nonlinearities. Some of the shortcomings of both models are briefly discussed. A third type of model, involving feedback, is tentatively proposed, which might more parsimoniously explain neurophysiological results.
认为耳蜗纤维放电率与强度函数曲线斜率的频率依赖性是基底膜频率依赖性非线性的证据这一观点，受到了一项论证的挑战，该论证表明这种斜率的频率依赖性可以从一个仅涉及线性滤波器和无记忆、频率无关非线性的耳蜗模型中推导出来。文中简要讨论了这两种模型的一些不足之处。还初步提出了第三种涉及反馈的模型，它可能能更简洁地解释神经生理学结果。
