iodopsin /io·dop·sin/ (i″ah-dop´sin) a photosensitive violet pigment found in the retinal cones of some animals and important for color vision.
iodopsin
i·o·dop·sin (   -d p s n)n. A violet, light-sensitive visual pigment found in the cones of the retina. Also called visual violet. |
iodopsin
[ī′ōdop′sin]
Etymology: Gk, ioeides + optikos, vision
a photosensitive chemical in the cones of the retina that reacts in association with other chemicals and plays a part in color vision. Iodopsin is more stable when exposed to bright light than rhodopsin, which is found in the rods of the retina. Color vision, a synthesis of red, green, and blue light, is induced by changes within the pigments of different types of cones during a photochemical process in which coded nerve impulses are sent to the brain. Research on the exact role of iodopsin in color vision, which is still unknown, is ongoing.
