Melanopsin, a light sensor that sets the circadian rhythm- the bodyâ€™s biological clock- also plays an important role in vision, according to this study.
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 mRGCs-it forwards information about the brightness of incoming light directly to conventional visual centers in the brain.
By studying the hydra, a member of an ancient group of sea creatures that is still flourishing, scientists at UC Santa Barbara have made a discovery in understanding the origins of human vision.
An international team of scientists has discovered how changes in both gene expression and gene sequence led to the diversity of visual systems in African cichlid fish.
Emory University researchers have identified the first fish known to have switched from ultraviolet vision to violet vision, or the ability to see blue light. The discovery is also the first example of an animal deleting a molecule to change its visual spectrum.
Researchers from the University of Washington and the University of Florida have used gene therapy to cure two adult monkeys of color blindness, successfully restoring full color vision to the animals.
The eyes of nocturnal bats possess two spectral cone photoreceptor types for daylight and colour vision. Reporting in the open-access, peer-reviewed journal PLoS ONE
Researchers from the John Hopkins School of Medicine have discovered a new type of cell used for vision in fish.
New article in the FASEB Journal reports that scientists have finally captured the elusive signaling device our retinas use to tell us what we see.
A team of Johns Hopkins neuroscientists has worked out how some newly discovered light sensors in the eye detect light and communicate with the brain.
