title: Chromatic patterns of cone photoreceptors. 1976 Glenn A. Fry Award Lecture.
abstract: The operations of vertebrate visual neurons must eventually be expressed in terms of the spectral classes and spatial distributions of photoreceptors that constitute inputs to those neurons. By using a cytochemical probe that permits visualization of the responses of cone photoreceptors to light stimulation, it has been possible to describe the spectral classes and spatial patterns of cones in a lower vertebrate, the goldfish, and in a primate, the baboon. This information is an important first step in analyzing the connections between cones and retinal neurons.
