Abstract

We develop an electronic circuit model of blue cone pathway in the primate retina, appending to the preceding midget cone system. Each compartment of the chromatic cell is composed of cascade connections of transadmittance followed by low pass filters and static nonlinear elements. Synaptic junctions among the cells are modeled by differential amplifiers or divisive elements with time lags. The dynamic response property of the blue cone pathway is predicted by the signal processing of the electronic circuit model.
