Binocular Integration in the Visual Cortex
Study of the monocular and binocular properties of neurones in the lightly anaesthetized feline striate cortex reveals a wealth of functional interactions which potentially underpin eye convergence and interocular alignment, and the encoding of visual perspective of three-dimensional objects. Monocularly, neurones’ relative preferences for opposing directions of motion, and selectivity for range of directions, are reliant upon the spatial-frequency content of perceived scenes. Each neurone’s directionality, spatial-frequency selectivity, eye preference and length selectivity, differs according to whether input is from contralateral or ipsilateral eyes, or binocular.
