Journal ArticleDOI
In search of the visual pigment template.
TL;DR: In this paper, the authors investigated the accuracy limits of putative universal templates for visual pigment absorbance spectra, and if possible to amend the templates to overcome the limitations, and concluded that the idea of universal templates remains valid and useful at the present level of accuracy of data on photoreceptor absorbance.
Journal ArticleDOI
Visual pigments and the photic environment: The cottoid fish of Lake Baikal

TL;DR: Data clearly show a correlation between photoreceptor complement, visual pigment lambda max and depth, but question the hypothesis that there is a correlation of pigmentlambda max with water colour since, in contrast to oceanic waters, the maximum transmission of Baikal water is between 550 and 600 nm.
Journal ArticleDOI
The photoreceptors and visual pigments of the garter snake (Thamnophis sirtalis): a microspectrophotometric, scanning electron microscopic and immunocytochemical study
TL;DR: The small single cones with the 360-nm pigment provide the garter snake with selective sensitivity to light in the near ultraviolet region of the spectrum, which might be important in localization of pheromone trails.
Journal ArticleDOI
Visual cycle: Dependence of retinol production and removal on photoproduct decay and cell morphology.
Petri Ala-Laurila,Alexander V. Kolesnikov,Rosalie K. Crouch,E. Tsina,Sergey A. Shukolyukov,Victor I. Govardovskii,Yiannis Koutalos,Barbara Wiggert,Maureen E. Estevez,M. Carter Cornwall +9 more
TL;DR: The more rapid rates of retinol production in cones compared to rods are consistent with the more rapid operation of the visual cycle in these cells, as well as the surface-to-volume ratio of the outer segment and the availability of ret inoid binding protein (IRBP).
Journal ArticleDOI
The frequency of isomerization-like 'dark' events in rhodopsin and porphyropsin rods of the bull-frog retina.
TL;DR: The low rate of isomerization‐like ‘dark’ events in bull‐frog rhodopin rods shows, firstly, that results cannot be generalized across species even for rhodopsins which appear spectrally identical, and suggests that these events need not (in an evolutionary sense) constitute an irreducible noise factor which must set the ultimate limit to the sensitivity of dark‐adapted vision.
