Robust visual cortex evoked potentials (VEP) in Gnat1 and Gnat2 knockout mice
Frontiers in Cellular Neuroscience, 2022 Intrinsically photosensitive retinal ganglion cells (ipRGCs) express the photopigment melanopsin, imparting to themselves the ability to respond to light in the absence of input from rod or cone photoreceptors.

Distinctive gene expression in the reduced first thoracic legs of a nymphalid butterfly. [PDF]
Insect Mol BiolTranscriptome analysis reveals that the small non‐walking front legs of a butterfly have distinct gene expression to the four walking legs. Reduced front legs express a gene with putative mechanosensory roles, a blue‐sensitive opsin and two homeobox genes.

Phototransduction in Drosophila [PDF]
Current Opinion in Neurobiology, 2015 Phototransduction in Drosophila's microvillar photoreceptors is mediated by phospholipase C (PLC) resulting in activation of two distinct Ca(2+)-permeable channels, TRP and TRPL. Here we review recent evidence on the unresolved mechanism of their activation, including the hypothesis that the channels are mechanically activated by physical effects of ...

Phototransduction in Drosophila [PDF]
Science China Life Sciences, 2012 The Drosophila visual transduction is the fastest known G protein-coupled signaling cascade and has been served as a model for understanding the molecular mechanisms of other G protein-coupled signaling cascades. Numbers of components in visual transduction machinery have been identified. Based on the functional characterization of these genes, a model

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.

Animal Cells and Systems, 2023 Visual impairment is occasionally observed in multiple sclerosis (MS) and its animal model, experimental autoimmune encephalomyelitis (EAE). Although uveitis and optic neuritis have been reported in MS and EAE, the precise mechanisms underlying the ...

Phototransduction Motifs and Variations [PDF]
Cell, 2009 Seeing begins in the photoreceptors, where light is absorbed and signaled to the nervous system. Throughout the animal kingdom, photoreceptors are diverse in design and purpose. Nonetheless, phototransduction-the mechanism by which absorbed photons are converted into an electrical response-is highly conserved and based almost exclusively on a single ...

Phototransduction and the Evolution of Photoreceptors [PDF]
Current Biology, 2010 Photoreceptors in metazoans can be grouped into two classes, with their photoreceptive membrane derived either from cilia or microvilli. Both classes use some form of the visual pigment protein opsin, which together with 11-cis retinaldehyde absorbs light and activates a G-protein cascade, resulting in the opening or closing of ion channels ...

Drosophila Photo-transduction Simulator
Journal of Open Research Software, 2013 This software contains detailed modelling of the single photon response, the quantum bump, of fly photoreceptors. All known components participating in the primary phototransduction process are taken into account, and estimates are given for both the ...

Frontiers 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—
