photoreceptors

A previously undetected pathway in the mouse brain bypasses the visual cortex to directly activate contagious itch.

After receiving an intraocular injection of the gene for a light-sensitive protein, a 58-year-old man diagnosed with the neurodegenerative eye disease retinitis pigmentosa was able to locate objects on a table using engineered goggles.

Researchers insert functioning cone photoreceptors into the retinas of mice with advanced eye disease, improving their vision.

The silver spinyfin has an extraordinary diversity of rod photopigments, which researchers propose may allow it to see color in the deep, dark sea.

Researchers injected the retinas of mice with nanoparticles that bound to photoreceptors and converted near-infrared light to green light that the animals could see.

Blind rats are made to see after sheets of cells implanted into their eyes make themselves at home.

Human eye organoids could help scientists develop therapies for colorblindness.

A double gene-transfer therapy transformed the non-neuronal cells into rod photoreceptors in the retinas of animal models of congenital blindness.

Scientists have discovered a new type of eye cell in a deep-sea fish species.

Optometrist and eclipse-chaser Ralph Chou describes how even a partially eclipsed sun can damage the eye.

Warmth acts on a light-sensing protein similarly to the way shade does, setting off a growth spurt in plant seedlings.

See how different environmental conditions affect the activity of a molecule sensitive to both light and temperature.

The roundworm uses a light receptor that resembles a type of taste receptor and is better at detecting UV light than human photoreceptors.

Specialized filters allow jumping spiders to see more colors than scientists previously thought.

An overview of visual processing

Retinal glial cells acting as optical fibers shuttle longer wavelengths of light to individual cones.

In mice, adult cone cell outer segments and their visual functions deteriorate if two microRNAs are not present.

Vision researcher John Dowling has spent a lifetime studying the neural architecture of the retina. He is closing his laboratory after 53 years, opting to extend these studies as a postdoc.

A crustacean’s eyes are tuned to ultraviolet frequencies with the help of a biological sunblock molecule.
