Light activates the brain in blind people

Light not only activates the brain, it does so even in people who can not see, researchers have found. Light enhanced brain activity during a cognitive task even in people who were totally blind, according to a study by researchers from the University of Montreal and Boston’s Brigham and Women’s Hospital.“We were stunned to discover that the brain still respond significantly to light in these rare three completely blind patients despite having absolutely no conscious vision at all,” said senior co-author Steven Lockley.
