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.

Visual Cone Arrestin 4 Contributes to Visual Function and Cone Health [PDF]
Visual arrestins (ARR) play a critical role in shutoff of rod and cone phototransduction. When electrophysiological responses are measured for a single mouse cone photoreceptor, ARR1 expression can substitute for ARR4 in cone pigment desensitization; however, each arrestin may also contribute its own, unique role to modulate other cellular functions.A ...

The Cone-specific visual cycle [PDF]
Cone photoreceptors mediate our daytime vision and function under bright and rapidly-changing light conditions. As their visual pigment is destroyed in the process of photoactivation, the continuous function of cones imposes the need for rapid recycling of their chromophore and regeneration of their pigment.

A novel cone visual cycle in the cone-dominated retina [PDF]
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.

Morphologic assessment of photoreceptors after idiopathic epiretinal membrane surgery with adaptive-optics SLO [PDF]
Purpose This study aims to quantitatively assess morphological alterations in cone cells following idiopathic epiretinal membrane (IERM) surgery using adaptive optics scanning light ophthalmoscopy (AO-SLO) and to correlate these findings with retinal ...

Physiological basis of resolution acuity in vision [PDF]
Vision is the primary sensory modality for many animals, especially humans and other primates. A fundamental constraint on visual resolution acuity is set by the size and spacing of cone photoreceptors, notably in theĀ fovea of the retina where cones are ...

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