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.
