Electronic circuit model of color sensitive retinal cell network

Abstract

An equivalent electronic circuit model is developed to analyze the response of color sensitive retinal cell network. Gap junction between adjacent cells is reduced by bi-directional conductance, and chemical synaptic junction between layers is reduced to uni-directional trans-admittance with time lag of first order. On the basis of the previous physiological studies, we estimate parameter values in the electronic circuit model. It is appreciated for the model to perform adequately the properties of spectral response andspatio-temp oral response. Frequency response of the network are also calculated.
