[Model studies of lateral inhibition as a mechanism of detecting motion. II. Modeling feedback inhibition].

A program is worked out which imitates non-stationary lateral inhibition in two-dimensional retina with physiologically real characteristics. Experiments with moving and flashing stimuli of different size are carried out. It is shown that lateral inhibition may serve as a mechanism which forms selective sensitivity of the elements involved to the movement of the stimuli. Recurrent inhibition proves to be more effective than the direct one providing that a longer delay in time exists. The results obtained are explained by the peculiarities of recurrent inhibition as the feedback system.
