![The best brain training app is NOT the one youre thinking of.
Brains. It would be great if we could train them, huh? But what if the best brain training app turns out to be a commercial video game? Some researchers put the brain training question to the test, comparing the benefits of the brain-training app Lumosity to the benefits of playing a regular, old game—Portal 2. The results, as they say on the internet, may surprise you.
