The Cortical basis of binocular vision


We reconciled a long-standing 40-year debate on the single-cell relationship between ocular dominance and binocular disparity in visual cortex with a very large sample of cells (> 2,000 neurons). We further showed that there a map for disparity in the primary visual cortex for the very first time. We used these data to propose a mechanism by which multiple depth cues could be quickly decoded (from locally orthogonal circuits) in the visual cortex.  Thus, important computations for binocular vision are likely occurring very early in the visual system, not in ‘higher order’ extra-striate visual areas.
