which lead to risk-taking behavior. Brain changes: Immaturity of the cortex and the
activity of the limbic system alter the adolescent's perception of both pleasure and
risk and potential consequences of behavior. Social context: Adolescents who are
alienated from adults and not yet attached to families of their own are more likely to
engage in risky behaviors.
