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 ...

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. Nature - Rod and Cone Responses in the Human Eye ...

The newly discovered cells are shaped like twisted tree branches and were found deep inside the retina of a rat's eye. Like the eye's rods and cones, the new cells contain chemicals that react to ...

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 ...

Scientists at the Jules Stein Eye Institute at the David Geffen School of Medicine at UCLA have discovered that certain ...

To address whether the cells identified in rodents and primates also exist in humans, Zaidi and colleagues first had to find patients who lacked functional rods and cones, but retained pRGCs—a ...
