Retinas in all mammals, from mouse to man, are made up of light-sensitive cells known as cones and rods, named for their shapes, which convert light into nerve signals that are then transmitted to ...

Rods are more sensitive to light than cones so they are useful for seeing in dim light. There are three different types of cone cells which produce colour vision. The amount of light entering the ...

Human eyes contain two types of photoreceptors, or nerve cells that detect light: rods and cones. Each photoreceptor contains light-absorbing molecules, called photopigments, that undergo a ...

Their findings have been published in Nature Communications. Vertebrate retinas contain photoreceptor cells that convert ...
