The 3D orientation of a surface can be specified by perspective, motion parallax or binocular disparity. Tsutsui et al. have found cells in the monkey intraparietal sulcus that responded to surface orientation defined only by a texture gradient. Most of these cells also responded to orientation defined only by binocular disparity.
