Magnetic Resonance Imaging (MRI) scans allow us to map the maturation of the brain.
This image illustrates brain development through early adulthood, with blue indicating the mature state. The prefrontal cortex (white circle), which governs judgment and decision-making functions, is the last part of the brain to develop. This may help explain why teens, who are more prone to participating in risk-taking behavior, are particularly vulnerable to drug abuse.
As a result of scientific research, we know that addiction is a disease that affects both brain and behavior.
