New York University biologists have identified a new mechanism for regulating color vision by studying a mutant fly named after Frank ('Ol Blue Eyes) Sinatra.
HELSINKI and BERGEN, Norway, August 11, 2011 /PRNewswire/ -- Valkee (http://valkee.com), inventor of the world's first bright-light headset, and scientists from the University of Oulu will present new findings on human brain's photosensitivity at the Scandinavian Physiology Society Annual Meeting 2011, August 12-14. Their research localized the OPN3 protein - known as the light-sensitive photoreceptor protein - in all of the 18 evaluated areas of the brain.
A "four-eyed" fish that sees simultaneously above and below the water line has offered up a dramatic example of how gene expression allows organisms to adapt to their environment.
Unlike conventional methods, with the so-called optogenetics, the researchers are able to target one cell type.
Researchers at the University of Gothenburg have shown that sea urchins see with their entire body despite having no eyes at all.
On rare occasion, the light-sensing photoreceptor cells in the eye misfire and signal to the brain as if they have captured photons, when in reality they haven't.
Biologists have uncovered a key regulatory mechanism used for gene expression in the visual system.
Turns out our sensitivity to seeing in color is not only due to cone cells in the retina, but also through the thyroid gland by controlling which visual pigment is produced in the cones.
New research from Mount Sinai School of Medicine has discovered that rhodopsin, a pigment of the retina that is responsible for the first events in the perception of light, may also be involved in temperature sensation.
A light-sensing receptor that's packed inside the eye's photoreceptor cells has an altogether surprising role in cells elsewhere in the body, Johns Hopkins scientists have discovered.
