Spatial structure of cone inputs to receptive fields in primate lateral geniculate nucleus

  title={Spatial structure of cone inputs to receptive fields in primate lateral geniculate nucleus},
  author={R. Clay Reid and Robert Shapley},
HUMAN colour vision depends on three classes of cone photoreceptors, those sensitive to short (S), medium (M) or long (L) wavelengths, and on how signals from these cones are combined by neurons in the retina and brain. Macaque monkey colour vision is similar to human, and the receptive fields of macaque visual neurons have been used as an animal model of human colour processing1. P retinal ganglion cells and parvocellular neurons are colour-selective neurons in macaque retina and lateral… Expand
Absence of spectrally specific lateral inputs to midget ganglion cells in primate retina
The absence of spectral specificity in the inhibitory wiring raises doubt about the involvement of midgetganglion cells in colour vision and suggests that colour opponency may instead be conveyed by a different type of ganglion cell. Expand
Space and Time Maps of Cone Photoreceptor Signals in Macaque Lateral Geniculate Nucleus
We studied neurons in the central visual field representation of the lateral geniculate nucleus (LGN) in macaque monkeys by mapping their receptive fields in space and time. The mapping was performedExpand

Color perception in macaque monkeys and humans depends on the visually evoked activity in three cone photoreceptors and on neuronal post-processing of cone signals, which are subdivided into classes of single-opponent cells and double-opp opponent cells. Expand
L and M Cone Contributions to the Midget and Parasol Ganglion Cell Receptive Fields of Macaque Monkey Retina
The results suggest that peripheral H1 and ganglion cells inherit their L and M cone inputs from the photoreceptor mosaic unmodified by selective circuitry, which is consistent with random connections in central retina. Expand

This review summarizes recent work relevant to receptive field structure of cells of the parvocellular (PC) and (MC) magnocellular pathways in the primate. In the PC-pathway, recent data suggest thatExpand
Horizontal Cells of the Primate Retina: Cone Specificity Without Spectral Opponency
The hypothesis that the opponent circuitry emerges from selective connections between horizontal cell interneurons and cone photoreceptors sensitive to long, middle, and short wavelengths (L-, M-, and S-cones) was tested by physiologically and anatomically characterizing cone connections of horizontal cell mosaics in macaques. Expand
The 'blue-on' opponent pathway in primate retina originates from a distinct bistratified ganglion cell type
The results thus demonstrate an anatomically distinct pathway that conveys S-cone signals to the brain, and the morphology of the blue-on cell suggests a novel hypothesis for the retinal circuitry underlying the blue–yellow opponent response. Expand

The primate retina is an exciting focus in neuroscience, where recent data from molecular genetics, adaptive optics, anatomy, and physiology, together with measures of human visual performance, areExpand
Dynamics of primate P retinal ganglion cells: responses to chromatic and achromatic stimuli
An improved method of systems analysis has allowed us to explore the dynamics of the colour‐opponent subregions of P‐cell receptive fields with a single chromatic stimulus, and shows that the centre and surround subregion of the P‐ cell receptive field have similar temporal responses, but the surround is slightly delayed. Expand
Spatiochromatic Interactions between Individual Cone Photoreceptors in the Human Retina
The spatial and spectral patterns of these interactions suggest that interneurons mediating lateral inhibition in the central retina, likely horizontal cells, establish functional connections with L and M cones indiscriminately, implying that the cone-selective circuitry supporting red–green color vision emerges after the first retinal synapse.

Cat and monkey retinal ganglion cells and their visual functional roles
Comparisons between cat and monkey ganglion cell classes reveal several important similarities between M cells and X cells, which are very sensitive to contrast. 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
Functional properties of ganglion cells of the rhesus monkey retina.
Three general classes of cells were identified in a sample of 460 cells recorded from all areas of the retina subserving the central 40 degrees of vision in the rhesus monkey, and colour‐opponent, broad‐band and non‐concentric cells were equally represented in all areas. Expand

It is reported that the parallel analysis of color and luminance in the visual scene begins in the retina, probably at a retinal site distal to the ganglion cells. Expand
Sensitivity of macaque retinal ganglion cells to chromatic and luminance flicker.
The modulation transfer function of phasic cells to luminance flicker was similar to the detection sensitivity curve of human observers who viewed the same stimulus, suggesting the different cell types are the substrate of different channels which have been postulated on the basis of psychophysical experiments.

Morphological Classification of Bipolar Cells of the Primate Retina
The data show that the P‐ and M‐cell pathways of the primate visual system are, to a significant extent, already anatomically discrete at the photoreceptor synapse. Expand

A new concept of retinal colour coding
A theory of retinal colour coding based closely on recent anatomical and physiological results is presented and opponent colour channels are shown to be an inevitable result of any randomly distributed retinal cone mosaic, remaining uninfluenced by a predominance of "red" or "green" cones. Expand
The two-dimensional spectral structure of simple receptive fields in cat striate cortex.
A quantitative, general purpose method was developed for measuring the responses of visual neurons to stimuli distributed with high resolution over the two-dimensional (2D) spatial frequency domain and the hypothesis that orientation and spatial frequency tuning are independent was tested by forming scaled radial and angular sections through 2D spectral response profiles.
