Single opsin driven white noise ERGs in mice [PDF]

open access: yesFrontiers in Neuroscience, 2023
PurposeElectroretinograms elicited by photopigment isolating white noise stimuli (wnERGs) in mice were measured. The dependency of rod- and cone-opsin-driven wnERGs on mean luminance was studied.MethodsTemporal white noise stimuli (containing all ...

Light does not phase shift the circadian clock of subcutaneous adipose tissue in vitro [PDF]

open access: yesnpj Biological Timing and Sleep
The retinal photopigment melanopsin is also expressed in subcutaneous white adipose tissue (scWAT). Through melanopsin, light can modulate scWAT metabolism, but its impact on circadian phase is unclear.

The HY5-PIF regulatory module coordinates light and temperature control of photosynthetic gene transcription. [PDF]

open access: yesPLoS Genetics, 2014
The ability to interpret daily and seasonal alterations in light and temperature signals is essential for plant survival. This is particularly important during seedling establishment when the phytochrome photoreceptors activate photosynthetic pigment ...

Melanopsin photopigment comes in two distinct forms. [PDF]

open access: yesPLoS Biology, 2006
Photoreceptors aren’t just for seeing. Deep within the retina of the vertebrate eye are photoreceptors that capture light to regulate non-visual processes such as day–night rhythms and the narrowing and widening of the pupil. To capture light, these special cells—called intrinsically photoreceptive retinal ganglion cells—require pigments called ...

Examining the role of the photopigment melanopsin in the striatal dopamine response to light [PDF]

open access: yesFrontiers in Systems Neuroscience
The mesolimbic dopamine system is a set of subcortical brain circuits that plays a key role in reward processing, reinforcement, associative learning, and behavioral responses to salient environmental events.

Blue light stimulation of the blind spot in human: from melanopsin to clinically relevant biomarkers of myopia [PDF]

open access: yesBioelectronic Medicine
The protective effects of time spent outdoors emphasize the major role of daylight in myopia. Based on the pathophysiology of myopia, the impact of blue light stimulation on the signaling cascade, from melanopsin at the blind spot to clinically relevant ...

Expression of Opsins of the Box Jellyfish Tripedalia cystophora Reveals the First Photopigment in Cnidarian Ocelli and Supports the Presence of Photoisomerases

open access: yesFrontiers in Neuroanatomy, 2022
Cubomedusae, or box jellyfish, have a complex visual system comprising 24 eyes of four types. Like other cnidarians, their photoreceptor cells are ciliary in morphology, and a range of different techniques together show that at least two of the eye types—

Extravisual opsins in the blind shrimp Creaseria morleyi: presence and expression

open access: yesNauplius, 2023
The presence of a long-wavelength sensitive (LWS) opsin gene was demonstrated in the stygobitic crustacean Creaseria morleyi (Creaser, 1936) by PCR readings from genomic DNA.
