Sanjay Gupta looks into modern brain research. Posit Science's Brain Fitness Program is one of the highlights. The BFP is geared towards regaining lost ground due to age/inactivity, and is comprised of 6 core "games", focused on auditory recognition and memory recall. Similar games, but focused on visual cues rather than audio, are in the works ("Cortex"). I have not demo'd this visual product yet, but a good online program can be found at www.lumosity.com (free 14 day trial - the birdwatching game is original and inventive.)
