MODELING THE MAINTENANCE OF HORIZONTAL PURSUITS WITH NEURAL NETWORKS .1. MOTION DETECTOR

A computational model for the maintenance of horizontal smooth pursuit eye movements of primates is presented. A motion detector circuit is discussed, which on detect multi-directional motion and explain not on ly neurophysiological phenomena, such as the selectivity for the direc tion and the velocity of a moving stimulus, but also psychophysical ph enomena, such as the change of displacement thresholds with stimulus v elocity and the perception of apparent motion. It is even anti-noise a nd can fairly discriminate a figure from its background.
