Amygdala is a part of the brain, which is an  interactive center of emotions, emotional behavior, and motivation. Scientists have figured out that teenagers use Amygdala more rather than prefrontal cortex because prefrontal cortex is not yet developed. Therefore, adolescents use their Amygdala to make decisions and make actions. However, because Amygdala is an interactive center of emotions, emotional behavior, and motivation, adolescents take an action of impulsive behavior.
