A Michigan State University study suggests a relationship between violent video games and a pattern of aggression in human brains.
But, like many of the other studies out there there are no definitive links between behavior and violent games.
The latest study does show how the brain reacts to violent video games.
The study results fall on the same week as MSU's Game Design and Technology Conference.
The conference hosted game developers, social scientists and legal experts on that and many other issues.
A constitutional law expert tells us that it may only be a matter of time before the video game industry is regulated by the government -- hoping to prevent the purchase of illicit games by minors.
Still, others say the concern over violent games may be overblown.
