In normal vision, the inputs from the two eyes are inte(cid:173) grated into a single percept. When dissimilar images are presented to the two eyes, however, perceptual integra(cid:173) tion gives way to alternation between monocular inputs, a phenomenon called binocular rivalry. Although recent evidence indicates that binocular rivalry involves a mod(cid:173) ulation of neuronal responses in extrastriate cortex, the basic mechanisms responsible for differential processing of con:6.icting Using a neural network that models the mammalian early visual system, I demonstrate here that the desynchronized fir(cid:173) ing of cortical-like neurons that first receive inputs from the two eyes results in rivalrous activity patterns at later stages in the visual pathway. By contrast, synchronization of firing among these cells prevents such competition.

In normal vision, the inputs from the two eyes are integrated into a single percept. When dissimilar images are presented to the two eyes, however, perceptual integration gives way to alternation between monocular inputs, a phenomenon called binocular rivalry.
