In the continuing debate over the dangers of violent videogames, new research shows the brain function of gamers is actually altered in as little as one week of play. Researchers at the Indiana University School of Medicine found a direct relationship between playing videogames and subsequent changes to portions of the brain associated with cognitive function and emotional control, according to Science Daily. The findings were presented at the annual meeting of the Radiological Society of North America. Researchers randomly assigned 28 young men aged 18 to 29 into two groups of 14. The young men had little previous exposure to violent video games.
