Daytime vision is mediated by retinal cones, which, unlike rods, remain functional even in bright light and dark-adapt rapidly. These cone properties are enabled by rapid regeneration of their pigment ...

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

Share on Pinterest New research involving cones and rods in the retina could lead to new treatments for vision loss. Gregory Adams/Getty Images Cone photoreceptors in retinal degeneration have been ...

The visual phototransduction cascade begins with a cis–trans photoisomerization of a retinylidene chromophore associated with the visual pigments of rod and cone photoreceptors. Visual opsins release ...

Rhodopsin and cone opsins are essential for light detection in vertebrate rods and cones, respectively. It is well established that rhodopsin is required for rod phototransduction, outer segment disk ...

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 ...

SEATTLE--(BUSINESS WIRE)--Acucela Inc., a clinical-stage biotechnology company focused on developing new treatments for blinding eye diseases, announced today that the first patient data from the ...

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 ...

Scientists have discovered rod and cone cells while examining the fossil of 300-million-year-old fish eyes. The findings suggest that the fish likely possessed color vision. Scientists found fossil of ...
