Photoreceptor cells in our eyes can adjust to both weak and strong light levels, but we still don't know exactly how they do it. Researchers now revealed that the photoreceptor protein rhodopsin forms ...

“The non-invasive in vivo optical imaging of rhodopsin activation extends the diagnostic capability of ORG and may facilitate ...

Photoreceptor cells in our eyes can adjust to both weak and strong light levels, but we still don't know exactly how they do it. Emeritus Professor Fumio Hayashi of Kobe University and his colleagues ...

For the first time, an international research team led by Nanyang Technological University, Singapore (NTU Singapore) has ...

New Orleans, LA – Research led by Minghao Jin, PhD, Assistant Professor of Ophthalmology and Neuroscience at the LSU Health Sciences Center New Orleans Neuroscience Center of Excellence, has found a ...

The biochemistry of vision is a complex process. The molecules supporting the visual pigments that allow us to see our surrounding reality have remained essentially invisible for scientists for a long ...

Scientists have identified two non-retinoid compounds that may be able to treat retinitis pigmentosa (RP), a group of inherited eye diseases that cause blindness. The compounds were discovered by ...

Scientists say that new experiments with mouse eye tissues strongly suggest that a longstanding 'textbook concept' about the way a mammal's retina processes light needs a rewrite. Johns Hopkins ...

First off, my name is a misnomer. I love physics like Lennie likes bunnies. So I was wondering today about the following: What happens to the photons that hit your eye and are recognized as light? The ...

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 ...
