Neuroscientists working to test brain training claims

The draw is huge: Play video games and get smarter. For the past decade, various groups have claimed that their programs do everything from staving off neurodegenerative disease to enhancing education and improving daily functioning. Absent from many of these claims has been neuroscientific evidence. Cognitive neuroscientists are now rigorously testing the potential benefits of such 'brain training' tools. New work is showing promising results.
