works\ Spatial Vision [1988: with Karen K. DeValois]
Detail: He showed that visual cortical neurons respond to frequency rather than edges or lines {direct spatial information} [1975]. They detect fundamental frequency and higher frequencies, together with orientation. He used gratings, checkerboards, and plaid patterns. Results matched results expected from analysis by Fourier transforms.
