By chromatic adaptation, all three cone mechanisms of rhesus monkey vision can be identified in single neurons of striate cortex. This trichromatic inter-action occurs in cells sensitive to color and indicates that striate cortical cells tend to be more wavelength discriminating than cells at lower stages of the primate visual system.
