The effects of dietary carotenoid supplementation and retinal carotenoid accumulation on vision-mediated foraging in the house finch. [PDF]
PLoS ONE, 2011 BACKGROUND: For many bird species, vision is the primary sensory modality used to locate and assess food items. The health and spectral sensitivities of the avian visual system are influenced by diet-derived carotenoid pigments that accumulate in the ...

Blue light regenerates functional visual pigments in mammals through a retinyl-phospholipid intermediate. [PDF]
, 2017 The light absorbing chromophore in opsin visual pigments is the protonated Schiff base of 11-cis-retinaldehyde (11cRAL). Absorption of a photon isomerizes 11cRAL to all-trans-retinaldehyde (atRAL), briefly activating the pigment before it dissociates ...

The retina visual cycle is driven by cis retinol oxidation in the outer segments of cones [PDF]
, 2017 Vertebrate rod and cone photoreceptors require continuous supply of chromophore for regenerating their visual pigments after photoactivation. Cones, which mediate our daytime vision, demand a particularly rapid supply of 11-cis retinal chromophore in ...

Visual adaptation of opsin genes to the aquatic environment in sea snakes
BMC Evolutionary Biology, 2020 Background Evolutionary transitions from terrestrial to aquatic life history cause drastic changes in sensory systems. Indeed, the drastic changes in vision have been reported in many aquatic amniotes, convergently.

Accelerated evolution of dim-light vision-related arrestin in deep-diving amniotes
Frontiers in Ecology and Evolution, 2022 Arrestins are key molecules involved in the signaling of light-sensation initiated by visual pigments in retinal photoreceptor cells. Vertebrate photoreceptor cells have two types of arrestins, rod arrestin, which is encoded by SAG and is expressed in ...

Functional Imaging of the Outer Retinal Complex using High Fidelity Imaging Retinal Densitometry [PDF]
, 2020 We describe a new technique, high fidelity Imaging Retinal Densitometry (IRD), which probes the functional integrity of the outer retinal complex. We demonstrate the ability of the technique to map visual pigment optical density and synthesis rates in ...

A new mouse model for retinal degeneration due to Fam161a deficiency
Scientific Reports, 2021 FAM161A mutations are the most common cause of inherited retinal degenerations in Israel. We generated a knockout (KO) mouse model, Fam161a tm1b/tm1b , lacking the major exon #3 which was replaced by a construct that include LacZ under the expression of ...
