Teenage Brain Networks Connected to Drug Risk (image) University of Vermont Share Print E-Mail Caption Newly discovered networks in the brain, shown here in color, go a long way toward explaining why some teenagers are more likely to start experimenting with drugs and alcohol. Diminished activity in some of these networks, discovered by two scientists at the University of Vermont and their European colleagues, makes some teens more impulsive -- and less able to inhibit urges to try alcohol, cigarettes and illegal drugs in early adolescence.
