Center-surround interactions in foveal and peripheral vision.

abstract：:Response properties of neurons in V3A were studied at a retinal eccentricity of 2-4 deg. The distributions of spatial frequency bandwidths and orientation bandwidths were similar to those of neurons in V1. Peaks of spatial frequency tuning curves ranged from 0.35 to 8.0 c/deg with a mean of 1.75 c/deg. Most V3A cells ...

Gratings which combined both color and luminance contrast yielded small aftereffects and no interocular transfer.

The visual stimulus is generated by drawing with uniform probability, at each refresh time, an image from a finite set S of orthonormal images.
