Researchers have discovered that a protein acts as a "self-avoidance enforcer" to ensure color-detecting cells in the retina ...

Unlike the cells we use in bright light, called cone cells, rod cells aren't great at seeing colors. Start the day smarter. Get all the news you need in your inbox each morning. In the ...

Vertebrate retinas contain photoreceptor cells that convert light into neural signals. These photoreceptors come in two main types: rods, which function in dim light; and cones, which function in ...

This is because our cone cells function best in relatively bright light. Other cells in our eyes, called rod cells, help us see in dim light. But because rod cells only have a single light-sensitive ...

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 ...
