For centuries, scientists
believed the human brain was fully formed in childhood and did not
change. But in recent years, studies have found the brain continues to
make new connections over a person’s lifetime. In 2008, researchers
found that older adults who engaged in brain-training drills could
improve cognitive abilities. This set off a flurry of new brain-training
websites promising users could slow memory loss and other effects of
aging. Now, millions of Americans visit these sites every day, playing
games and solving puzzles. But critics say the online training doesn’t
have real-life benefits. Diane and a panel of experts discuss the surge
in brain game applications and whether or not they work.
