The first study to look at the direct effect of videogames on teen brains documents functional differences between violent and nonviolent play.

For nearly 35 years, Americans have lived with videogames—and the controversy surrounding them. Proponents say the games are fun and even help teach kids how to use logic to solve problems. Critics say the more violent games—including some that reward players for killing innocent bystanders and police—increase aggressive thoughts and antisocial behavior.
Unfortunately, the debate has suffered from a dearth of empirical evidence about the effect of videogames. Now, a new brain-imaging study from Indiana University—the first of its kind—suggests that playing violent videogames may indeed change the way a person feels and acts. In the study, released Tuesday at the at the annual meeting of the Radiological Society of North America, researchers found that teenagers who played a violent videogame exhibited increased activity in a part of the brain that governs emotional arousal. The same teens showed decreased activity in the parts of the brain involved in focus, inhibition and concentration. See: This is your brain on violent video games
