Violent Video Games Alter Human Brain

Scientists from  Indiana University School of Medicine recently conducted an experiment in which 22 men( aged 18 to 29 ) were tested in order to observe changes that video games may cause in human brains. The men were divided into two groups. One of these has to play continously for 10 hours for the fist week and remain calm for the second week. The second group, on the other hand, did not play at all in the two-week period.

After the two week period, all 22 men weent through (1) emotional interference task, pressing buttons according to the color of visually presented words (words indicating violent actions were interspersed among nonviolent action words) and (2)a cognitive inhibition counting task.

According to the MNT report :
"After just one week of violent game play, the video game group members showed less activation in the left inferior frontal lobe during the emotional task and less activation in the anterior cingulate cortex during the counting task, compared to their baseline results and the results of the control group after one week. After the second week without game play, the changes to the executive regions of the brain were diminished."
