US - Study: Effects of violent games linger in brain

Teens who play violent video games show increased activity in areas of the brain linked to emotional arousal and decreased responses in regions that govern self-control, a study presented at the Radiological Society of North America's annual meeting found. The study used functional magnetic resonance imaging to record tiny metabolic changes in brain activity in 44 adolescents who were asked to perform a series of tasks after playing either a violent or nonviolent video game for 30 minutes.
