Better known as the light sensor that sets the body's biological clock, melanopsin also plays an important role in vision: Via its messengers-so-called melanopsin-expressing retinal ganglion cells, or ...

Over the past two decades there have been significant advances in our understanding of both the anatomy and function of the melanopsin system. It has become clear that rather than acting as a simple ...

For most, the time spent staring at screens -- on computers, phones, iPads -- constitutes many hours and can often disrupt sleep. Now, researchers have pinpointed how certain cells in the eye process ...

Melanopsin, a blue photoreceptor in retinal cells, receives blue light each morning and transmits the signal via the nerves of the eye to the SCN, the circadian rhythm central pacemaker. The photo ...

Better known as the light sensor that sets the body's biological clock, melanopsin also plays an important role in vision: Via its messengers-so-called melanopsin-expressing retinal ganglion cells, or ...

(Medical Xpress)—Light is inextricably intertwined in myriad ways with most life on Earth. In humans, for example, light stimulates alertness and cognition, improving performance and increasing ...

Researchers from Imperial College London, Johns Hopkins University, USA and Brown University, USA have discovered that melanopsin, a recently identified protein, plays a key role in a completely new ...

(Medical Xpress)—A team of researchers in Belgium has found that people exposed to orange light exhibit greater brain activity than those exposed to blue light. In their paper published in Proceedings ...

DNA aptamers of melanopsin that regulate the clock hands of biological rhythms were developed by the Toyohashi University of Technology and the National Institute of Advanced Industrial Science and ...

Melanopsin (OPN4) is a light-sensing protein found in skin and retina cells. A new study conducted at the University of São Paulo (USP) in Brazil suggests that OPN4 can also participate in the ...

At top left, an X-gal stained retina from a mouse heterozygous for a LacZ knockin at the melanopsin locus reveals axons coursing toward the optic disc. At top right, a melanopsin antibody labels cell ...
