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 ...

C-opsin Expressing Photoreceptors in Echinoderms [PDF]

Integrative and Comparative Biology, 2013
Today's progress in molecular analysis and, in particular, the increased availability of genome sequences have enabled us to investigate photoreceptor cells (PRCs) in organisms that were formerly inaccessible to experimental manipulation. Our studies of marine non-chordate deuterostomes thus aim to bridge a gap of knowledge regarding the evolution of ...

Expression of Non-visual Opsins Opn3 and Opn5 in the Developing Inner Retinal Cells of Birds. Light-Responses in Müller Glial Cells

Frontiers in Cellular Neuroscience, 2019
The avian retina is composed of different types of photoreceptors responsible for image and non-image forming tasks: the visual photoreceptor cells (cones and rods), the melanopsin-expressing intrinsically photoresponsive retinal ganglion cells (ipRGCs ...

Identification and Expression Patterns of Opsin Genes in a Forest Insect, Dendrolimus punctatus

Insects, 2020
Dendrolimus punctatus walker (Lepidoptera: Lasiocampidae) is the most serious coniferous forest defoliator in China. This species has long life history, and shows different activity rhythms and light response behaviors at larval and adult stages.

Optogenetics and deep brain stimulation neurotechnologies [PDF]

, 2015
Brain neural network is composed of densely packed, intricately wired neurons whose activity patterns ultimately give rise to every behavior, thought, or emotion that we experience. Over the past decade, a novel neurotechnique, optogenetics that combines

Long-wavelength sensitive opsin (LWS) gene variability in Neotropical cichlids (Teleostei: Cichlidae)

Anais da Academia Brasileira de Ciências
Cichlid fishes are an important group in evolutionary biology due to their fast speciation. This group depends widely of vision for feeding and reproduction.

Melanopsin-expressing retinal ganglion cells are resistant to cell injury, but not always [PDF]

, 2017
Melanopsin retinal ganglion cells (mRGCs) are intrinsically photosensitive RGCs deputed to non-image forming functions of the eye such as synchronization of circadian rhythms to light-dark cycle.

Thermal constraints on in vivo optogenetic manipulations. [PDF]

, 2019
A key assumption of optogenetics is that light only affects opsin-expressing neurons. However, illumination invariably heats tissue, and many physiological processes are temperature-sensitive.

Light Activation of the Phosphoinositide Cycle in Intrinsically Photosensitive Chicken Retinal Ganglion Cells [PDF]

, 2010
Purpose: In vertebrates, intrinsically photosensitive retinal ganglion cells (ipRGCs) acting as nonvisual photoreceptors transmit environmental illumination information to the brain, regulating diverse non–image-forming tasks.
