A potential role for binocular integration without binocular disparity information in primary visual cortex

Abstract

How information from both eyes aligns in the primary visual cortex (V1) depends on the vergence of the eyes and the depth of a given object, resulting in a particular binocular disparity. However, a significant fraction of V1 neurons are binocular but not modulated by binocular disparity, raising the question of how their outputs can be meaningful.
