A model for lateral inhibition is presented in the context of the auditory channel. The mechanical analyzing system of the inner ear cannot alone account for the frequency resolution of hearing. Some additional mechanism, possibly lateral inhibition located in the auditory neural network, is needed to achieve the frequency selectivity observed in electrophysiological and psychoacoustical experiments. In a computer simulation study, the shape of an ideal lateral inhibition function was obtained. Such a function is applicable to all sensory modalities. In hearing, this function permits the sharpest possible frequency resolution as it can completely remove the frequency desharpening effect of the mechanical properties of the basilar membrane. In vision, it can compensate for abberations caused by the imperfections of the optical system of the eye.
本文在听觉通道的背景下提出了一种侧抑制模型。内耳的机械分析系统本身无法解释听觉的频率分辨率。需要一些额外的机制，可能是位于听觉神经网络中的侧抑制，来实现电生理和心理声学实验中观察到的频率选择性。在一项计算机模拟研究中，获得了理想侧抑制函数的形状。这样的函数适用于所有感觉模态。在听觉中，该函数允许尽可能精确的频率分辨率，因为它可以完全消除基底膜机械特性造成的频率锐化效应。在视觉中，它可以补偿眼睛光学系统不完善引起的像差。
