Simulation of a Visual Receptor Network

An analogue method is presented for simulating a visual receptor network of the type described by Hartline, Ratliff, and Miller as a model for inhibitory interaction in the retina. The number of elements required in the model is reduced drastically by using a process of repeated approximation which converges. The activity of a large receptor field is simulated by breaking it up into much smaller, overlapping subfields, the activity of which can be determined using the model equations.
