A 58-year-old man who has been blind for years now sees well enough to make out shapes, including the white lines of a crosswalk. The advancement comes thanks to a technology called ...

Opsin, the ligand-free form of the G-protein-coupled receptor rhodopsin, at low pH adopts a conformationally distinct, active G-protein-binding state known as Ops*. A synthetic peptide derived ...

BOSTON, MA (Nov. 01, 2022) SIONYX, a leader in color digital night vision technology, brings innovation to the market with the introduction of OPSIN DNVM1, a helmet-mounted, color digital night ...

They give us our richly detailed daytime colour vision. A fourth kind of opsin is present in so-called rod cells, which are more sparsely distributed over the rest of the retina. Rods support our ...

They used an opsin -- a protein that occurs in the brain and eyes -- from zebrafish and introduced it into the brain of mice. Unlike other optogenetic tools, this opsin is not switched on but ...

Most mammals have two spectral cone types containing either of two visual pigments (opsins), one sensitive to shortwave light (UV/blue opsin), the other to middle-to-longwave light (green opsin).

Researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered a light-sensitive opsin protein that plays a surprising and possibly critical role in neuron maturation and ...

While previous studies have suggested that mammals might express opsin proteins outside the eye, there was little information on what functions they might influence. A study published Oct. 10 in ...

Scientists discovered years ago that the hypothalamus—which helps to manage body temperature, hunger, sex drive, sleep and more—includes neurons that express the protein opsin 3 (OPN3).
