The majority of ganglion cells in the retina of goldfish have receptive fields organized so that the cells respond particularly to simultaneous contrasts of color. The receptive fields are concentrically arranged. If the cell is excited by red light in the center, then it will also be excited by green light in the periphery, and inhibited by green light in the center or red light in the periphery. The occurrence of this arrangement and the reverse is about equal. The receptive field is much… Expand
Retinal Color Mechanisms
Color vision depends on cone photoreceptors with different spectral sensitivities, and the red/green system in human and macaque is the midget system, with high acuity; the yellow/blue system has lower acuity, and there are fewer blue photoreceptor cells. Expand
Retinal bipolar cells with double colour-opponent receptive fields
It is reported that, in the carp at least, this stage of information processing occurs earlier, as double colour-opponent receptive fields are found among the retinal bipolar cells of this animal. Expand
Ganglion Cells with Sustained Activity in the Fish Retina and Their Possible Function in Evaluation of Visual Scenes
The simultaneous operation of feature detectors and ganglion cells with baseline activity separated into ON and OFF channels is represented retinotopically and may provide tectum opticum neurons with the visual scene information required for their function of controlling external attention. Expand

There are four recognized types of cell involved in color vision, and some are single color opponent cells, where the response to a particular wavelength does not vary from one part of the receptive field to another. Expand

Red–green (or red–cyan) cells, along with blue–yellow and black–white cells, establish three chromatic axes that are sufficient to describe all of color space. Expand
Signals for color and achromatic contrast in the goldfish inner retina
The present results provide a parallel with the well-known principle of human color vision, first proposed by Kirschmann as the third law of color contrast, and may also have implications for the evolution of vertebrate color vision. Expand
Goldfish retina: a correlate between cone activity and morphology of the horizontal cell in clone pedicules.
In the cone pedicules, the digitations of horizontal cell process lateral to the synaptic ribbon disappear after dark adaptation. This disappearance is correlated with the loss of color opponency andExpand

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
Color Vision in Fishes and Its Neural Basis
To establish the neural basis of color vision and other visual functions a neuropharmacological approach in combination with behavioral experiments yields promising results, which indicate that there is a parallel processing of “color” and high visual acuity on the one hand, and “motion,” “flicker,’ and ”brightness” detection on the other hand, which is similar to the situation in the visual system of primates. Expand
The notion of a receptive field is fundamental for the understanding of the physiological basis of perception as the nervous system is not designed simply for the transmission of so many bits ofExpand


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

It is shown that the responses to luminance and chromaticity are separated at the retinal level in the goldfish, and De Valois has shown that they are partly separated in the lateral geniculate body of the monkey. Expand
Functional basis for "on"-center and "off"-center receptive fields in the retina.
The ganglion cells in the goldfish retina may have either “on’-center or “off”-center receptive fields and the response evoked by a stimulus of any size and at any location within the receptive field represents the sum of the contributions from both the “ on” and “ off” processes. Expand
