Purpose: The temporal characteristics of dichoptic contrast integration across space in primary visual cortex are relatively unknown. This study investigated the effect of varying interstimulus interval (ISI) and flank duration on contrast detection threshold (CDT) of a sinusoid target under monoptic, dichoptic and half-binocular viewing. Methods: Eleven subjects with normal vision participated for a mean of 25 hours each. In the main experiment, target and flanks were 3 cpd vertical sinusoids with 6 lambda (sigma = 1.5 lambda) center-to-center vertical separation. Flank contrast was normalized to 3X flank CDT. Flanks were presented at 4 durations (67-500ms) and ISIs were presented …
