Final answer:
Images of brains exposed to violent video games exhibit marked differences. Correlations have been found between violent media content and aggressive thoughts and behavior. No definitive evidence supports a direct link between violent media exposure and physical violence or criminal behavior.

Scholars have found correlations between violent media content and aggressive thoughts and behavior. However, while some studies suggest a link between violent media exposure and aggression, there is no definitive evidence that violent media directly causes physical violence or criminal behavior.
