分析了Cascade模型中视锥到水平细胞的前向和后向反馈通道,建立了基于Cascade模型的Hopfield网络结构,并提出了不同类型水平细胞的电位变化量相互关系的相角与光波长值的映射关系,建立了模拟这一过程的CMAC网络结构。研究表明,不同类型水平细胞的电位变化量的时相特性,以某种方式对光输入的波长值进行了编码。

This article analyzes the forward and backward feedback pathways between cones and horizontal cells in the Cascade model and sets up a Hopfield Network to simulate the interaction mechanism.Additionally,it appears that the phase character of horizontal cell is connected with spectrum and a CMAC Network is established to simulate the mapping process.This article aims to indicate that the mapping of horizontal cell and spectrum might be the underlying way for retina to code the signal from spectral input.
