A Simulation of Receptive Fields in the Vertebrate Visual System by Electronic Circuits

Abstract

This paper is concerned with a simple model of the vertebrate visual system, the model being constructed by electronic circuits. The neural networks in the visual system are considered as multilayer spatio-temporal circuits.
A neuron unit was simulated by electronic circuits-4 transistors and 5 diodes-and, then, a simple model simulating the vertebrate visual system was constructed by them.This model consists of a receptor cell layer (photo-diodes layer) and 4 neuronal layers and can detect edges, moving objects, and corners of stimulated patterns automatically.
Such a model seems to be useful for neurophysiological studies of the visual system in living organisms.
