SummaryWe report on experiments which were undertaken in an attempt to clarify mechanisms underlying the contrast effects of chromatic surround illumination on spectral responsiveness of cells in the parvocellular layers of the LGN (P-LGN-cells), that had been demonstrated under standard conditions in the preceding companion paper. The experiments were done in anesthetized macaques (Macaca fascicularis). In some neurons, S-potentials were recorded together with the post-synaptic action… 

The neurophysiological correlates of colour and brightness contrast in lateral geniculate neurons

The direction of changes of spectral responsiveness of P-LGN-cells are consistent with psychophysical colour contrast and colour induction effects which imply that light of one spectral region in the surround reduces the contribution of light from that same spectral area in the (broad band or composite) object colour.

Responses of spectrally selective cells in macaque area V2 to wavelengths and colors.

Although spatiotemporal wavelength comparisons are taking place in the color-specialized subdivisions of area V2, the determination of complete color-constant behavior at the neuronal level requires further processing, in other areas.

Effect of background colors on the tuning of color-selective cells in monkey area V4.

It is concluded that neurons in area V4 exhibit the property of color constancy and that their response properties are thus able to reflect color perception.

Correlation between visual stimulus eccentricity and multiscale neuronal activity in the lateral geniculate nucleus

The results confirm that the local field potentials as a measure of the mesoscopic level neuronal activity provide additional information concerning the activity of neuronal populations, thus enhancing the present knowledge about the functional circuitry as the foundation of various neuronal processes.

Visual Contextual Effects of Orientation, Contrast, Flicker, and Luminance: All Are Affected by Normal Aging

The perception of older and younger observers on a battery of tasks designed to assess visual contextual effects is compared, and it is suggested that normal aging produces a generalized, non-specific alteration to contextual processing in vision.

The model's prediction of complementary color by color induction is not in agreement with previous suggested mechanisms, the suggested neuronal locus of the mechanism and the assumptions of previous studies that assumed that a complementary effect cannot be derived from an opponent receptive field type.

Central and Peripheral Visual Function: Effects of Age and Disease

Both foveal and paracentral regions of the retina were investigated, with emphasis on both pregeniculate and postgeniculate impairments, to establish how ageing and disease affect the thresholds for detection of stimulus structure, motion and colour.

An account of responses of spectrally opponent neurons in macaque lateral geniculate nucleus to successive contrast

Cell activity can be related to cone excitation in a trichromatic colour space with the help of the model, to give an indication of suprathreshold coding of colour and lightness.

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.

Neuronal representation of spectral and spatial stimulus aspects in foveal and parafoveal area 17 of the awake monkey

61 cells were tested for monocular vs. binocular input, and single neurons without consistant visual responses could not be driven by any of the visual stimuli, and may play a role also for cortical representation of textures.

Colour and brightness signals of parvocellular lateral geniculate neurons

Yellow sensitive W-cells with a narrow spectral sensitivity peaking around 570 nm and with only a small or no response to white light, could enable distinction between white and yellow of similar luminance, consistent with the opponency model of spectrally sensitive cells in the LGB.

A quantitative study of chromatic organisation and receptive fields of cells in the lateral geniculate body of the rhesus monkey

The responses of neurones in the lateral geniculate nucleus (LGN) were investigated in anaesthetised rhesus monkeys and it was found that the receptive fields from which wavelength-dependent excitatory or suppressive effects could be elicited are concentrically superimposed.

The cytochrome oxidase-rich patches or blobs of the monkey striate cortex have been shown to contain cells that have unoriented receptive fields, many of which are color selective. We studied the

Color vision mechanisms in monkey striate cortex: dual-opponent cells with concentric receptive fields.

The cumulative evidence presented in this paper indicates that the concentric cells probably received direct geniculate inputs and, therefore, they are the first cortical stage in the integration of color-contrast information.

It is suggested that a typical V4 neuron sums inputs that ultimately derive from several thousand ganglion or parvocellular dLGN cells, and “color contrast” may be computed in V4.

Receptive Field Structure of P and M Cells in the Monkey Retina

The concept of P and M retinogeniculate channels has emerged from attempts to explain the layering of the primate Lateral Geniculate Nucleus, and it is revealed that the different types of cell layers in the LGN receive afferent input from differenttypes of retinal ganglion cells.
