Single opsin driven white noise ERGs in mice
Frontiers 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 ...

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

Action spectra of zebrafish cone photoreceptors. [PDF]
PLoS ONE, 2013 Zebrafish is becoming an increasingly popular model in the field of visual neuroscience. Although the absorption spectra of its cone photopigments have been described, the cone action spectra were still unknown. In this study we report the action spectra

Light control of G protein signaling pathways by a novel photopigment. [PDF]
PLoS ONE, 2018 Channelopsins and photo-regulated ion channels make it possible to use light to control electrical activity of cells. This powerful approach has lead to a veritable explosion of applications, though it is limited to changing membrane voltage of the ...

An EvoDevo Study of Salmonid Visual Opsin Dynamics and Photopigment Spectral Sensitivity
Frontiers in Neuroanatomy, 2022 Salmonids are ideal models as many species follow a distinct developmental program from demersal eggs and a large yolk sac to hatching at an advanced developmental stage. Further, these economically important teleosts inhabit both marine- and freshwaters

Chlorophyll treatment combined with photostimulation increases glycolysis and decreases oxidative stress in the liver of type 1 diabetic rats [PDF]
Brazilian Journal of Medical and Biological Research, 2019 Photodynamic therapy (PDT) promotes cell death, and it has been successfully employed as a treatment resource for neuropathic complications of diabetes mellitus (T1DM) and hepatocellular carcinoma.

The Diversity and Adaptive Evolution of Visual Photopigments in Reptiles
Frontiers in Ecology and Evolution, 2019 Reptiles are a highly diverse class that consists of snakes, geckos, iguanid lizards, and chameleons among others. Given their unique phylogenetic position in relation to both birds and mammals, reptiles are interesting animal models with which to ...

Extraocular, rod-like photoreceptors in a flatworm express xenopsin photopigment
eLife, 2019 Animals detect light using opsin photopigments. Xenopsin, a recently classified subtype of opsin, challenges our views on opsin and photoreceptor evolution.
