Detail: He lived 1926 to ? and studied visual-cortex organization, with Torsten Wiesel. Not using eye during critical or sensitive period to detect stimulus features makes visual cortex unable to detect stimulus features.
Brain detects color in round vertical columns, located 0.5 mm apart in regular arrays between primary-visual-cortex orientation columns, using double-opponent neurons, with both ON-center and OFF-center circular fields, to compare colors. He found blobs by staining primary visual cortex with cytochrome oxidase (CO), with Margaret Livingstone. Interblob regions detect orientation.
