The entire structure consisting of the two molecules becomes a photopigment.

In this case, the virus was used to insert photopigment genes.

Upon gaining the gene, the cone begins to express the new photopigment.

Dark adaptation is the recovery of many photopigment molecules in the receptor.

The subject should first be evaluated to identify which photopigment they need to gain trichromacy.

Cones that gained the missing genes began expressing the new photopigment.

The photopigment gene is called melanopsin, which helps detect colors.

The photopigment found in rod cells is called rhodopsin.

It is yet unknown how the animals that gain a new photopigment are perceiving the new color.

This photopigment is depolarized in the presence of light, unlike the rods which are hyperpolarized.

Four photopigment opsins exist in teleost fish, reptiles and birds.

The wavelength sensitivity is determined by the rhodopsin photopigment.

The photopigment rhodopsin intercepts light as the first step in the perception of light.

Their eyes include three different kinds of cones, each containing a different photopigment (opsin).

"Photopigment conversions expressed in pupil mechanism of blowfly visual sense cells."

"Rays have more than one photopigment and so they have the retinal 'machinery' for color vision," he added.

The outer cell segment contains a photopigment.

In medical terminology, "photopigment" commonly refers to the photoreceptor proteins of the retina.

The behavior of the rhodopsin photopigment explains why the human eye cannot resolve lights with different spectral power distributions under low light.

Merely giving the monkeys red-sensing photopigment receptors would not necessarily give them the ability to perceive red, the researchers knew.

The RGCs use the photopigment melanopsin to absorb the light energy.

The researchers concluded that integrating the stimulus from the new photopigment as an adult was not analogous to vision loss following visual deprivation.

The xanthophyll cycle takes place, along with other photopigment reactions, in the membranes of thylakoids within chloroplasts.

The evolutionary process of switching from a single photopigment to two different pigments would have provided early ancestors with a sensitivity advantage in two ways.

Densitometric measurement of human cone photopigment kinetics.
