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...

Journal of Vision article suggests potential treatment for blindsight patients Although we assume we can see everything in our field of vision, the brain actually picks and chooses the stimuli that come into our consciousness. A new study in the Association for Research in Vision and Ophthalmology's Journal of Vision reveals that our brains can be trained to consciously see stimuli that would normally be invisible. Lead researcher Caspar Schwiedrzik from the Max Planck Institute for Brain...

Two Kansas State University psychology researchers have found that although central vision allows our eyes to discern the details of a scene, our peripheral vision is most important for telling us what type of scene we're looking at in the first place, such as whether it is a street, a mountain or a kitchen. "I think the most surprising part of the study is that we didn't really expect peripheral vision to do that well at getting the gist of a scene," said Adam Larson, K-State master's...

Research shows for the first time that the brain can latch on to color and assign it to a different object Color is normally thought of as a fundamental attribute of an object: a red Corvette, a blue lake, a pink flamingo. Yet despite this popular notion, new research suggests that our perception of color is malleable, and relies heavily on biological processes of the eye and brain. The brain's neural mechanisms keep straight which color belongs to what object, so one doesn't mistakenly see a...

BOSTON, Aug. 31 /PRNewswire/ -- A high-tech device that expands the visual field of patients with tunnel vision has passed a collision test in a walking simulator, according to scientists at Schepens Eye Research Institute, in a study published in the September issue of Investigative Ophthalmology and Visual Science. The study found that patients wearing this innovative device, consisting of a tiny camera, pocket-sized computer and a transparent computer display on a pair of glasses, were...
