Unit responses of the rabbit lateral geniculate nucleus to monochromatic light on the retina.

Seven unique wavelength responses, two inhibitory and five excitatory, with sensitivity maxima from 435 to 635 millimicrons, have been recorded from light-adapted, non-albino rabbits. Several combinations, usually one excitatory with one inhibitory response, often having characteristics suggesting mutual antagonism between them, were observed from single lateral geniculate cells.
