Like a spotlight that illuminates an otherwise dark scene, attention brings to mind specific details of our environment while shutting others out. A new study by researchers at the Salk Institute for Biological Studies shows that the superior colliculus, a brain structure that primarily had been known for its role in the control of eye and head movements, is crucial for moving the mind's spotlight. Their findings, published in the Dec. 20, 2009, issue of the journal Nature Neuroscience, add...

The development of a bionic eye that will restore vision to someone who is completely blind is a step closer after the research team working on the project detected signals in the brain from electrodes implanted in the retina of a living eye. The project, led by Associate Professor Michael Ibbotson from The Vision Centre and The Australian National University, has been investigating how artificial electrical signals can be converted into meaningful biological signals in the eye. It uses a...

NORTH CHICAGO, Ill., Nov. 30 /PRNewswire/ -- Using a high-output camera to film the back of the human eye, for the first time researchers have shown that a resveratrol-based (rez-vair-ah-trawl) nutriceutical matrix can effectively remove cellular debris from the human eye that accumulates with advancing age and correlated this with significant improvement in visual acuity and night vision in an 80-year old man. Resveratrol is widely known as a red wine molecule. To view the Multimedia News...
