A novel cone visual cycle in the cone-dominated retina [PDF]
Experimental Eye Research, 2007 The visual processing of humans is primarily reliant upon the sensitivity of cone photoreceptors to light during daylight conditions. This underscores the importance of understanding how cone photoreceptors maintain the ability to detect light. The vertebrate retina consists of a combination of both rod and cone photoreceptors.

CRALBP supports the mammalian retinal visual cycle and cone vision [PDF]
Journal of Clinical Investigation, 2015 Mutations in the cellular retinaldehyde-binding protein (CRALBP, encoded by RLBP1) can lead to severe cone photoreceptor-mediated vision loss in patients.

Metabolic rescue of cone photoreceptors in retinitis pigmentosa
Taiwan Journal of Ophthalmology, 2021 Retinitis pigmentosa (RP) encompasses a group of inherited retinal dystrophies characterized by the primary degeneration of rod and cone photoreceptors. It is a leading cause of visual disability, with an incidence of ~1 in 7000 persons. Although most RP

Visual Pigments of Goldfish Cones [PDF]
The Journal of General Physiology, 1974 Freshly isolated retinal photoreceptors of goldfish were studied microspectrophotometrically. Absolute absorptance spectra obtained from dark-adapted cone outer segments reaffirm the existence of three spectrally distinct cone types with absorption maxima at 455 ± 3,530 ± 3, and 625 ± 5 nm.

Retinal cone photoreceptors of the deer mouse Peromyscus maniculatus : development, topography, opsin expression and spectral tuning [PDF]
, 2013 A quantitative analysis of photoreceptor properties was performed in the retina of the nocturnal deer mouse, Peromyscus maniculatus, using pigmented (wildtype) and albino animals.

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2014 Cone visual pigments are visual opsins that are present in vertebrate cone photoreceptor cells and act as photoreceptor molecules responsible for photopic vision. Like the rod visual pigment rhodopsin, which is responsible for scotopic vision, cone visual pigments contain the chromophore 11-cis-retinal, which undergoes cis-trans isomerization resulting

APPLICATION OF DANDELIN’S THEOREM TO DRAWING CIRCLES IN PARALLEL PERSPECTIVE
Journal of Industrial Design and Engineering Graphics, 2017 The paper analyses a problem of great theoretical importance in practice of perspective: the nature of the perspective of a circle from the horizontal plane according to the relative position between the spectator plane (parallel to the picture plane ...
