Preferred phase disparity as a function of receptive field orientation (DeAngelis et al., 1991). Each dot gives the peak of the Gaussian fit to single-cell responses to disparate drifting sinusoidal gratings in anesthetized cat striate cortex. The closer the orientation preference of the cell to horizontal, the more confined is the tuning of the cells to small values of phase disparity. The solid line is a sinusoid indicating the relative maximum phase disparity for component orientations of a broadband pattern with horizontal disparity.
