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. All subjects had a visual acuity of 6/12 or ...

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 ...

Both image photodetector arrays and retinas are pixelated sensors that dynamically extract various features from the visual scene—e.g., color, brightness, and contrast—before transmitting electrical ...

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 ...

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 ...

Share on Pinterest New research involving cones and rods in the retina could lead to new treatments for vision loss. Gregory Adams/Getty Images Cone photoreceptors in retinal degeneration have been ...

Scientists have discovered rod and cone cells while examining the fossil of 300-million-year-old fish eyes. The findings suggest that the fish likely possessed color vision. Scientists found fossil of ...

In addition to allowing us to see, the mammalian eye also detects light for a number of "nonvisual" phenomena. A prime example of this is the timing of the sleep/wake cycle, which is synchronized by ...
