Video games attack the brains of teenagers

Video games attack the brains of teenagers


Violent video games stimulate activity in the brain regions of adolescents associated with emotions and reduce responses in areas responsible for rationing and self-control, an American study shows.
The specialists randomly chose 44 teenagers, between the ages of 13 and 17, who never had behavioral problems. Half of the young people played a 30 minute video game with a violent military subject, while the others played a non-violent but demanding game.
Finally, the participants performed concentration and inhibition measurement tests, while the brain was scanned using magnetic resonance imaging. Those who were given the violent game showed a greater activity in the amygdala, the seat of emotional arousal in the brain, and the rest showed a greater stimulation in the prefrontal area of ​​the brain, associated with intellectual concentration and self-control.

"Violent video games can have different short-term effects on brain function compared to non-violent but interesting video games," says Vincent Mathews, a radiology professor at Indiana University School of Medicine.
