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 ...

Researchers have discovered a way to revitalize cone receptors that have deteriorated as a result of retinitis pigmentosa. Working with animal models, researchers have discovered that replenishing ...

In addition to rod photoreceptor loss, many mutations in rod photoreceptor-specific genes cause degeneration of other neuronal types. Identifying mechanisms of cell–cell interactions initiated by ...

Scientists have long believed that the eye uses the retina’s rod cells for vision at night and cone cells to see during the day. New research at The Ohio State University Medical Center, however, ...

Researchers at the Johns Hopkins University School of Medicine and Washington University School of Medicine have identified a key to eye development — a protein that regulates how the light-sensing ...

Light-sensitive cells in the retina come in two main types: rods and cones. Rods are used for vision at low light and cones for color and bright light. A study in the September issue of the Journal of ...

Retinas from our earliest vertebrate ancestors had cone-like photoreceptors, presumably allowing them to see in daylight, but little ability to see at night. Then, millions of years ago in the ...
