Blind man walking: With no visual awareness, man navigates obstacle course flawlessly

Researchers have demonstrated for the first time that people can successfully navigate an obstacle course even after brain damage has left them with no awareness of the ability to see and no activity in the visual cortex, a region of the brain's cortex that is primarily responsible for processing visual inputs. The findings published in the December 23rd issue of Current Biology, a Cell Press publication, reveal the importance of alternative routes in the brain, which are active in both those who have suffered severe brain damage to the visual cortex and in all of our everyday lives, according to the researchers.
