[ Watch the Video ] Research could lead to new rehabilitative therapies when visual cortex is damaged 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? Yes, according to Tony Ro, a neuroscientist at the City College of New York, who is artificially recreating a condition called blindsight in his lab. "Blindsight...

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...

ROCHESTER, N.Y., March 31 /PRNewswire-USNewswire/ -- By doing a set of vigorous visual exercises on a computer every day for several months, patients who had gone partially blind as a result of suffering a stroke were able to regain some vision, according to scientists who published their results in the April 1 issue of the Journal of Neuroscience. Such rigorous visual retraining is not common for people who suffer blindness after a stroke. That's in contrast to other consequences of stroke,...

It has been discovered that a blind person could navigate through a maze of obstacles unaided using the power of sense alone. A man left blind by a stroke was able to intuitively walk around chairs and boxes without bumping into them using hidden pathways in the brain. According to the study, we all use subconscious brain resources and can do things we think we are unable to do. Research was published in Current Biology by the Harvard Medical School. The patient was left blind after damage to...
