Influence of Color Vision Impairments on Shade Matching among Dental Students
Medical Sciences Forum, 2023 This study examined the impact of color vision deficits on shade selection accuracy among 119 Portuguese dental students. Only males displayed color vision deficiencies (4/119).

Neural circuits in the mouse retina support color vision in the upper visual field
bioRxiv, 2019 Color vision is essential for an animal’s survival. It starts in the retina, where signals from different photoreceptor types are locally compared by neural circuits. Mice, like most mammals, are dichromatic with two cone types.

X link color blind: A systematic review of congenital color vision deficiency cognitively and neurologically [PDF]
SHS Web of Conferences, 2023 Color vision deficiency (CVD) can affect people’s perception and limits what job they takes. In order to distinguish colors, different cones differ in spectral sensitivity to capture photons.

Relation of eye dominancy with color vision discrimination performance ability in normal subjects [PDF]
International Journal of Ophthalmology, 2013 AIM: To evaluate the performance of dominant eye (DE) for color vision discrimination ability among the medical students with normal color vision.CONCLUSION: The color vision discrimination performance ability was found prominent for DE. This superiority

Diverse Cell Types, Circuits, and Mechanisms for Color Vision in the Vertebrate Retina.
Physiological Reviews, 2019 Synaptic interactions to extract information about wavelength, and thus color, begin in the vertebrate retina with three classes of light-sensitive cells: rod photoreceptors at low light levels, multiple types of cone photoreceptors that vary in spectral

Color vision in anterior ischemic optic neuropathy
American Journal of Ophthalmology Case Reports, 2020 Purpose: The non-arteritic form of anterior ischemic optic neuropathy (AION) is the most common acute optic neuropathy among individuals over the age of fifty, yet little is known about how the disorder affects color vision. We tested the hypothesis that

Endocrine regulation of multichromatic color vision
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance Primate and fish genomes contain tandemly replicated cone opsin genes. The human long wavelength-sensitive/medium wavelength-sensitive (LWS/MWS) tandem array underlies trichromatic color vision; mutations in this array cause altered color ...

Nonlinearities and Adaptation of Color Vision from Sequential Principal Curves Analysis [PDF]
Neural Computation, 2016 Mechanisms of human color vision are characterized by two phenomenological aspects: the system is nonlinear and adaptive to changing environments. Conventional attempts to derive these features from statistics use separate arguments for each aspect.

Reconciling Color Vision Models With Midget Ganglion Cell Receptive Fields
Frontiers in Neuroscience, 2019 Midget retinal ganglion cells (RGCs) make up the majority of foveal RGCs in the primate retina. The receptive fields of midget RGCs exhibit both spectral and spatial opponency and are implicated in both color and achromatic form vision, yet the exact ...
