New research in mice suggests that 'dormant' cone photoreceptors in the degenerating retina are not dormant at all, but continue to function, producing responses to light and driving retinal activity ...

New UCLA research in mice suggests that "dormant" cone photoreceptors in the degenerating retina are not dormant at all, but continue to function, producing responses to light and driving retinal ...

We measured monocular visual function—high-contrast visual acuity (HC-VA), central visual fields (mean sensitivity, MS), colour vision (desaturated Panel D-15), Pelli–Robson (P–R), and cone- and ...

After taking a neuroscience or biology course, most students have heard about rods and cones. But what about the recently discovered third class of photoreceptor cells in the retina - intrinsically ...

In addition to allowing us to see, the mammalian eye also detects light for a number of “non-visual” phenomena. A prime example of this is the timing of the sleep/wake cycle, which is synchronized by ...

Gene therapy has partly restored the function of the retina's cone receptors in two children who were born completely colourblind, reports a new study. Gene therapy has partly restored the function of ...

Gene therapy restored colour vision to colourblind children with the inherited retinal disorder achromatopsia, in the first trial of its kind in two paediatric patients. The finding shows that gene ...

A study on ground squirrels shows, not only do mitochondria produce bioenergy in the cone-shaped photoreceptors in the retina of the eye, they also act as micro-lenses that redirect light to the ...

Like ours, the fish visual system relies on light-sensitive receptors in the retina called rods and cones: Rods for twilight vision, cones for daylight vision. Researchers examining a 300-million-year ...
