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

This is a confocal microscope image of rod and cone photoreceptors in a human retina. Fluorescent probes have been used to identify rod photoreceptors (green) and cone photoreceptors and horizontal ...

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 ...

THERE is abundant evidence to show that the human eye has two distinct receptor mechanisms, one for vision in bright daylight and the other for vision at night. The sensitivity of the former, the ...

Peripheral vision is what you see beyond your direct line of sight. It helps provide a complete sense of your surroundings without moving your head. Jump to Key Takeaways. Within the eye, rods and ...

Dr. David Berson spoke yesterday at the Morrill Science Center on his research and discoveries about the relationship between eye cells, called ganglion, and the biological clock, a mechanism in ...

A gene therapy that significantly improves vision in a form of Leber congenital amaurosis (LCA) does not slow global degeneration of photoreceptors, according to a report published online January 22 ...

Discovery of a gene in zebrafish that triggers congenital blindness could lead to a suitable cure for similar disease in humans. Newborns babies can be at risk of congenital blindness, presenting ...

When humans finally have the chance to explore Mars, the members of those crewed missions will be millions of miles from home with delayed communications. Before they go, scientists want to understand ...
