Adolescent choices are shaped by a brain that is still developing, especially in systems involved in reward, emotion, planning, and self-control. Understanding this development helps explain why exciting or socially rewarding situations can sometimes outweigh caution in the moment.
The frontal lobe, including the prefrontal cortex, supports planning, rational decision-making, emotion regulation, and impulse control. These abilities continue to develop during adolescence. The limbic system is a collection of structures involved in emotion processing, memory formation, and sensory integration. It includes brain circuits that respond to rewarding experiences.
