Study shows that better gamers have bigger brains, are better learners
While we can't say for sure that videogames, as your grandmother insists, do indeed rot your brain, thanks to research conducted at a variety of Universities around the States we know that better gamers tend to have more gray matter than others -- at least in certain areas. Kirk Erickson, Ann Graybiel, Arthur Kramer, and Walter Boot worked together to form a study in which 39 participants' brains were scanned before those subjects were asked to play a game called Space Fortress (which looks a little like an Atari-era Geometry Wars). Players with larger nucleus accumbens did better learning the game early on, while those with larger caudate nucleus and putamen did better at playing with distractions. There was no sign that playing games actually increased the size of those areas of the brains, meaning some people are just born with a Power Glove on -- and that it's only a matter of time before MRIs replace aptitude tests.
