Microspectrophotometric measurements of retinal receptors are reported for eight species of Old World monkey. Although the animals vary greatly in size, colourings and habitat, they all appear to be trichromats and the peak sensitivities of their cones invariably lie near 430, 535 and 565 nm. This consistent pattern contrasts with the results reported earlier for New World monkeys and with the results reported here for Tupaia glis. The trichromacy of frugivorous catarrhine monkeys may have co…

The cone photoreceptors and visual pigments of chameleons
Visual pigments, oil droplets and photoreceptor types in the retinas of four species of true chameleons have been examined by microspectrophotometry and appear to be mixtures of rhodopsins and porphyropsins.
Spatial and temporal response properties of the major retino-geniculate pathways of Old and New World monkeys
Several spatial and temporal properties of parvo- and magnocellular cell s (which are identical for dichromatic and trichromatic animals) are compared.
The Genetic and Evolutionary Drives behind Primate Color Vision
The mechanism leading to trichromacy, with one exception, is based on a single polymorphic LWS gene, from which different allelic variants encode pigments with differing spectral peaks.
Uniformity of colour vision in Old World monkeys
Direct comparisons of the spectral sensitivity functions ofOld World monkeys suggest there are no significant variations in the spectral positions of the cone pigments underlying the trichromatic colour vision of Old World monkeys.
The spatial arrangement of cones in the primate fovea
Direct microspectrophotometric measurements of patches of foveal retina from Old World monkeys are made, and it is reported here that the distribu tion of long- and middle-wave cones is locally random.
The Genetics of Color Vision and Congenital Color Deficiencies
Red-green color blindness is not associated with loss of acuity, although this is present in a rare form of dichromacy called Bornholm eye disease where cone dysfunction and myopia is also present, and the recessive disorder of achromatopsia where all cone classes may be absent.

A model of retinal coding of natural spectra, based on discrimination thresholds, is used to examine the usefulness of dichromatic and trichromatic vision for finding fruit, and for identifying fruit and leaves by colour.
Photoreceptors, visual pigments, and ellipsosomes in the killifish, Fundulus heteroclitus: A microspectrophotometric and histological study
It is proposed that UV and S cones may be used to detect targets of interest against the background irradiance sensed by double cones.
Alouatta Trichromatic Color Vision: Cone Spectra and Physiological Responses Studied with Microspectrophotometry and Single Unit Retinal Electrophysiology
Recording from retinal ganglion cells of the same animals used for MSP measurements found MC cells and PC cells in the Alouatta retina with similar properties to those previously found in the retina of other trichromatic primates.


The visual pigments of rods and cones in the rhesus monkey, Macaca mulatta.
If the long wave‐length and middle wave-length cone pigments of the rhesus monkey are assumed to be identical to those of man and if additional assumptions are made about the lengths of human outer segments and about prereceptoral absorption, it is possible to derive psychophysical sensitivities that closely resemble the pi5 and pi4 mechanisms of W. S. Stiles.
Microspectrophotometric demonstration of four classes of photoreceptor in an old world primate, Macaca fascicularis.
1. Microspectrophotometric measurements reveal four classes of photoreceptor in the retina of the cynomolgus monkey, Macaca fascicularis, which is known to possess colour vision similar to that of a
Visual pigments in the four-eyed fish, Anableps anableps
The absorbance spectra of the photoreceptors are measured, and it is reported here that the same visual pigments are present in the dorsal and ventral regions of Anableps retina.
Variations of colour vision in a New World primate can be explained by polymorphism of retinal photopigments
Good quantitative agreement was found when the microspectrophoto-metrically measured absorbance spectra were used to predict the behavioural sensitivity of individual animals to long wavelengths and suggests that the behavioural variation arises from variation in the retinal photopigments.
Spectral sensitivity of cones of the monkey Macaca fascicularis.
Psychophysical results on human colour matching were well predicted from the spectral sensitivities of the monkey cones, and the spectra of the red and green cones matched the respective pi 5 and pi 4 mechanisms of Stiles (1953, 1959).
The purpose here is to outline some of the problems implicit in the use of MSP on retinal cells and to provide a more extensive perspective on the unique applicability of M SP to problems of photoreceptor physiology and biophysics in general.
Human visual pigments: microspectrophotometric results from the eyes of seven persons
Both patients were classified as normal trichromats by all clinical tests of colour vision but there was a clear difference in their relative sensitivities to long-wave fields, which proved to be that required by the microspectrophotometric results.
