VISUAL PIGMENTS IN SINGLE RODS AND CONES OF THE HUMAN RETINA. DIRECT MEASUREMENTS REVEAL MECHANISMS OF HUMAN NIGHT AND COLOR VISION.

Abstract

Difference spectra of the visual pigments have been measured in single rods and cones of a parafoveal region of the human retina. Rods display an absorption maximum (lambdamax) at about 505 mmicro associated with rhodopsin. Three kinds of cones were measured: a blue-sensitive cone with Amaxe about 450 mpf; two green-sensitive cones with Xmaa about 525 mumicro; and a red-sensitive cone with lambdamax about 555 mmicro These are presumably samples of the three types of cone responsible for human color vision.
