Latest Visual system Stories
People rely on their eyes for most things they do – yet the information provided by our visual sensing system is often distorted, unreliable and subject to illusion.
Scientists funded by the Medical Research Council (MRC) have shown for the first time that transplanting light-sensitive photoreceptors into the eyes of visually impaired mice can restore their vision.
Working in mice, scientists at Washington University School of Medicine in St. Louis have devised a treatment that prevents the optic nerve injury that occurs in glaucoma, a neurodegenerative disease that is a leading cause of blindness.
It's a chilling thought--losing the sense of sight because of severe injury or damage to the brain's visual cortex. But, is it possible to train a damaged or injured brain to "see" again after such a catastrophic injury?
The brain appears to be wired more like the checkerboard streets of New York City than the curvy lanes of Columbia, Md., suggests a new brain imaging study.
When observing a fly buzzing around the room, we should have the impression that it is not the fly, but rather the space that lies behind it that is moving.
For the first time, scientists at the University of Wisconsin-Madison have made early retina structures containing proliferating neuroretinal progenitor cells using induced pluripotent stem (iPS) cells derived from human blood.
If you are looking for a particular object — say a yellow pencil — on a cluttered desk, how does your brain work to visually locate it?
