After taking a neuroscience or biology course, most students have heard about rods and cones. But what about the recently discovered third class of photoreceptor cells in the retina - intrinsically ...

The retina is the layer of cells positioned at the back of your eyeball. This layer senses the light that comes into your eyeball and sends signals to your brain. The key retina parts include the rods ...

Under twenty-first-century metropolitan conditions, almost all of our vision is mediated by cones and the photopic system, yet cones make up barely 5% of our retinal photoreceptors. This paper looks ...

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. It is the first time ...

A: Zebrafish retinas at 3 days-post-fertilization (dpf). The neural retina consists of six major classes of neurons including two types of photoreceptors, rods and cones. B: Rod and cone ...

Like ours, the fish visual system relies on light-sensitive receptors in the retina called rods and cones: Rods for twilight vision, cones for daylight vision. Researchers examining a 300-million-year ...

International research team may be beneficial for new treatments for patients suffering from loss of vision in bright light, report investigators. An international research team headed by Thomas Münch ...

Why does the side of my vision see better than the centre of my vision in the dark? originally appeared on Quora: the knowledge sharing network where compelling questions are answered by people with ...

KUMAMOTO, Japan, Dec. 24 (UPI) --Rods and cones, the two main photoreceptor cells, are vital to human sight -- converting visible electromagnetic radiation into information our brains can use. And it ...

Vision, which consists of an optical system, receptors and image-processing capacity, has existed for at least 520 Myr. Except for the optical system, as in the calcified lenses of trilobite and ...
