Scientists have discovered a fossilized fish so well preserved that the rods and cones in its 300-million-year-old eyeballs are still visible under a scanning electron microscope.

Researchers have developed a noninvasive technique that can capture images of rod and cone photoreceptors with unprecedented detail. The advance could lead to new treatments and earlier detection ...

Like the eye's rods and cones, the new cells contain chemicals that react to light and send signals directly to the brain.

Because of rods' and cones' different functions, nocturnal animals (such as lab mice) tend to have retinas rich in rods. On the other hand, diurnal animals like the tree squirrel and tree shrew ...

From their distribution in the retina and in different animals, the cones are thought to be the photopic receptor organs and the rods the scotopic.

There’s a relay race in your eye that allows you to see. It begins when light hits the rod and cone cells in your retina, triggering a cascade of electrical signals. These pass through other ...

Cones work in bright light and register detail, while rods work in low light, detecting motion and basic visual information. It is the rods that become highly specialized in nocturnal animals.

We investigated the cone- and rod-mediated mfERG in 17 eyes of 17 subjects with early ARM and 16 eyes of 16 age-matched control subjects with normal fundi.

The eye has two kinds of photoreceptors that convert light into electrical activity: rods and cones. It is necessary to “divide the labor” between two cell types to enable the eye to see over ...

A fish fossil suggest rods and cones, the two main components of modern vision, have been around for more than 520 million years.
