Additivity of retinal and pursuit velocity in the perceptions of depth and rigidity from object-produced motion parallax.

abstract：:Two experiments were conducted on the orientation anisotropy in which averaged visual evoked potentials (VEPs) were recorded from the occipital scalp. The first experiment confirmed the findings of Maffei and Campbell (1970) that obliquely oriented gratings alternated back and forth produced smaller-amplitude VEPs tha...
