Answer:
The prefrontal cortex and the limbic system.
Step-by-step explanation:
The prefrontal cortex is responsible for executive functions such as decision-making, impulse control, and weighing the consequences of actions. It is involved in analyzing risks and making rational decisions based on long-term goals.
The limbic system, on the other hand, is associated with emotions, rewards, and pleasure. It includes structures such as the amygdala and the nucleus accumbens, which play a role in processing emotions and evaluating rewards and risks.
During adolescence, the prefrontal cortex is still developing and maturing, while the limbic system undergoes significant changes. This imbalance in the development of these two brain systems can lead to a heightened sensitivity to rewards and emotions while lacking fully developed impulse control and decision-making abilities.
As a result, teenagers may be more prone to engaging in risky behaviors as they are more likely to be driven by immediate rewards and emotions rather than considering long-term consequences. This imbalance in brain development can contribute to behaviors such as experimenting with drugs and alcohol, reckless driving, or engaging in unsafe sexual activities.
