Lrit1, a Retinal Transmembrane Protein, Regulates Selective Synapse Formation in Cone Photoreceptor Cells and Visual Acuity

Cell Reports, 2018
Summary: In the vertebrate retina, cone photoreceptors play crucial roles in photopic vision by transmitting light-evoked signals to ON- and/or OFF-bipolar cells.

Cone Opsins and Inherited Retinal Disease [PDF]

Cells
Opsins are the light receptors in retinal rod and cone photoreceptor cells that initiate vision in response to a light stimulus. Rhodopsin is the opsin in rods, and the influence of mutations that disrupt its structure and function has been characterized

Ultrafast Transient Absorption Spectra and Kinetics of Rod and Cone Visual Pigments

Molecules, 2023
Rods and cones are the photoreceptor cells containing the visual pigment proteins that initiate visual phototransduction following the absorption of a photon.

Childhood-onset genetic cone-rod photoreceptor diseases and underlying pathobiology

EBioMedicine, 2021
Inherited retinal diseases (IRDs) were first classified clinically by history, ophthalmoscopic appearance, type of visual field defects, and electroretinography (ERG).

Objective assessment of foveal cone loss ratio in surgically closed macular holes using adaptive optics scanning laser ophthalmoscopy. [PDF]

PLoS ONE, 2013
PURPOSE: To use adaptive optics scanning laser ophthalmoscopy (AO-SLO) to quantify cone loss ratio in the foveola in order to assess foveal cone status and to investigate relationships between foveal structural abnormalities and visual function in ...

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

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 ...

Colour opponency is widespread across the mouse subcortical visual system and differentially targets GABAergic and non-GABAergic neurons

Scientific Reports, 2023
Colour vision plays many important roles in animal behaviour but the brain pathways processing colour remain surprisingly poorly understood, including in the most commonly used laboratory mammal, mice.
