Abstract: In this study averaged visually evoked potentials were used to examine the nature of binocular processing of the visual system. Two different hypotheses have been proposed by earlier writers. The first assumed that the information from any one is suppressed at a given time, while the information from the other eye dominates in perception. An alternative hypothesis proposes that all information is processed and fused into a single percept. These two hypotheses were studied by manipulating the between line distances of grid patterns presented to the two eyes. Previously, characteristic responses have been found for the various pattern sizes. Again these differences were substantiated and were used to determine the contribution of each eye's input to the binocular responses. Pattern sizes presented to one eye were varied while holding constant the size of the pattern presented to the other. Three scalp recording sites were used: a midline occipital and two lateral occipital locations. Only the midline data was presented here. Averaged Visually Evoked Responses were obtained to each condition in a Binocular, Right, Binocular, Left flash order.
