The retina is the light-sensing part of the visual system and is composed of six neuron types and several non-neuronal cell types, with an estimated over 100 subtypes exist based on cell morphology, ...

Electrical synapses containing Connexin 36 (Cx36) represent the main means for direct electrical communication among neurons in the mammalian nervous system. However, little is kn ...

Pictured is mouse optic nerve and retina, responsible for relaying information from the eye to the brain. The tissue has been fluorescently stained to reveal the distribution of astrocytes (yellow), ...

Retinitis pigmentosa retinal degeneration is caused by a family of hereditary mutations in nearly 100 genes that slowly lead to blindness over years or decades. One of those genes encodes the enzyme ...

Taken with a specialized camera, images of a mouse retina before spaceflight (left) and a fluorescein angiogram, captured using a fluorescent dye, of the microvascular circulation of a mouse retina ...

Scientists in South Korea have developed experimental contact lenses designed to send electrical signals through the retina ...

Note: The video above shows a three-dimensional rotating view of three different cell types in the retina. The Campana cell (center) is shown flanked by two other cell classes that it is similar to, a ...
