Abstract

A theoretical general model of layered computation in the retina is presented. Each layer is functional in the sense that it may correspond or not to an anatomical layer. It is formed by computing elements which can perform in principle any non-linear arbitrary function on a three-dimensional input space. This space consists of 2 spatial dimensions, plus time. The function performed by each computing element of a layer is simplified for the cases of invariance, space or time linearity and for time independence. Two illustrations are also presented. The first is a model of the simple ganglion cells in cat's retina. The second, a model of the group 2 ganglion cell of the frog's retina.

摘要

提出了一种视网膜分层计算的理论通用模型。每一层在功能上可能对应或不对应解剖学层面。它由计算元件构成，这些元件原则上可以在三维输入空间上执行任何非线性任意函数。这个空间由两个空间维度加上时间组成。对于不变性、空间或时间线性以及时间独立性的情况，层中每个计算元件执行的函数被简化。还给出了两个示例。第一个是猫视网膜中简单神经节细胞的模型。第二个是青蛙视网膜中第2组神经节细胞的模型。
