The receptive fields of certain ganglion cells in the goldfish retina have been mapped. These fields are "off" center. "on-off" intermediate, and "on" periphery types. The excitatory process controlling the "on" response is stimulated maximally by green light; the "off" response process, inhibitory in nature, is stimulated maximally by red light. The two processes can be light adapted independently. 
Receptive Fields of Opponent Color Units in the Optic Nerve of the Ground Squirrel
Monochromatic stimuli revealed that each receptive field was composed of two mutually antagonistic components which had different spectral sensitivities and different spatial distributions. Expand
Trichromatic Mechanisms in Single Cortical Neurons
By chromatic adaptation, all three cone mechanisms of rhesus monkey vision can be identified in single neurons of striate cortex and indicates that striate cortical cells tend to be more wavelength discriminating than cells at lower stages of the primate visual system. Expand

Results suggest that interactions among three neuronal structures, the receptor, the horizontal cell, and the bipolar cell, produce the basic receptive field organization in the channel catfish. Expand
The Origin of “on” and “off” Responses of Retinal Ganglion Cells
The ganglion cell is the final common pathway into the optic nerve through which the information regarding the stimulus must flow and in the complex pattern of the responses of this cell the authors can search for information on the controlling factors. Expand
Spatial and chromatic interactions in the lateral geniculate body of the rhesus monkey.
The opponent principle, in which spatially separated excitatory and inhibitory regions are pitted against each other, has now been observed for retinal ganglion cells in the frog, the lizard, the rabbit, the rat, the ground squirrel, and the monkey. Expand

Tectal cell responses were distinguished by large visual fields, spontaneity, multiple spikes and long latencies to optic nerve stimulation, failure to follow above 60 per sec, plasticity of response. Expand
Regions of response transition of color-coded retinal units and an attempted, analogy to behavioral response transition
Electrophysiological responses obtained from single color-coded red-green ganglion ceils of the goldfish retina were analyzed in terms of the spectral region within which response transitions occur.Expand

Spectral sensitivity curves were derived from calibrated light flashes of various luminances, wavelengths, and durations delivered to the eye of the intact bullfrog under scotopic and photopic conditions by determining the relative energy at the various wavelengths required to produce a criterion latency.

Color-dependent distribution of spikes in single optic tract fibers of the cat.
Post-stimulus-time histograms of spike responses of some fibers in the cat's optic tract showed well-defined differences when diffuse white and colored flashes were presented, and some optic axons were selectively excited or inhibited by steady light of a particular wavelength. Expand
The Physiological Basis of Simultaneous Contrast in the Retina
The loci of contrast effects in the visual system have been a subject of controversies in the literature of vision. Among others, Helmholtz (9) was firm in his opinion that simultaneous contrastExpand
