visual pigment

There are far too few visual pigments for that.

In order to see this red color, these dragonfish have two different visual pigments.

By comparison, humans have only four visual pigments, three dedicated to see colour.

Rods have a high area for visual pigment and thus substantial efficiency of light absorption.

The result is bleaching of the visual pigments and temporary blindness for up to 40 minutes.

In fact, some aquatic animals have up to ten different classes of visual pigment in their eyes.

Each outer segment disc contains thousands of visual pigment molecules.

Even shallow water animals make the most of the ambient light by tuning all their visual pigments to blue.

Fish vision is mediated by four visual pigments that absorb various wavelengths of light.

They also produce visual pigments throughout their body, and may sense light levels directly from their body.

Vitamin A is required in the production of rhodopsin, the visual pigment used in low light levels.

RPE65 is important for the production of 11-cis retinal during visual pigment regeneration.

The evidence suggests that oil droplets respond to natural selection faster than the cone's visual pigments.

One photon hitting a visual pigment molecule can beget a neural response.

Due to their troglobitic lifestyle, thermosbaenaceans lack visual pigments and are therefore blind.

By definition, that requires that they have color receptors containing at least two different visual pigments.

Many New World monkeys have only two opsins, the visual pigments sensitive to particular colors of light.

The rods contain a rose-colored visual pigment and it is that which actually undergoes the chemical change with light.

These extra cone receptor visual pigments detect energy of other wavelengths, including sometimes ultraviolet.

Certain components of the eye, such as the visual pigments, appear to have a common ancestry: that is, they evolved once, before the animals radiated.

An example is light-activated rhodopsin, the visual pigment in photoreceptor cells of the retina.

The droplets, which contain high concentrations of carotenoids, are placed so that light passes through before reaching the visual pigment.

Rods, which contain the visual pigment rhodopsin are better for night vision because they are sensitive to small quantities of light.

A tenth class of visual pigment is found in the dorsal and ventral hemispheres of the eye.

It has three visual pigments located in different parts of the retina which likely allows color discrimination, each having distinct spectral sensitivities.
