Study Notes
Brain Development and Reward System
- The brain's reward center is particularly active during adolescence, releasing dopamine when teens take risks, have fun, or achieve success.
- This dopamine release is what makes these rewarding experiences feel good, motivating teens to seek out new and exciting activities.
- The prefrontal cortex, responsible for logic and reasoning, is still developing in adolescents, leading to less careful consideration of risks and rewards.
- This can result in behavior that seeks immediate rewards without considering long-term consequences.
The Role of the Prefrontal Cortex
- The prefrontal cortex develops from the back to the front, with the last region to fully develop being the prefrontal cortex, which is responsible for decision-making, planning, and future thinking.
- This region is often compared to Spock from Star Trek, as it is logical, calm, and collected.
The Lymbic System
- The limbic system, located deeper in the brain, is associated with emotions and immediate gratification, and can be likened to Captain Kirk from Star Trek – impulsive and emotional.
- The limbic system matures more quickly than the prefrontal cortex during adolescence.
The Striatum and Reward Sensitivity
- The striatum is a key part of the brain's reward system, becoming active when individuals receive rewards such as money and food.
- Researchers at UCLA found that the adolescent brain is much more sensitive to rewards like sugar and money compared to the brains of adults and children.
- This heightened sensitivity to rewards helps adolescents learn more quickly and efficiently from their environment.
Risk-Taking Behavior in Adolescence
- The striatum is also linked to risk-taking behavior. Teens with a more reactive striatum are more likely to be engaged in risky activities and enjoy them.
- Adolescence is a time for exploration and learning, and risk-taking, while potentially problematic, is a natural part of this process.
- It's more beneficial to provide opportunities for healthy risks, rather than trying to prevent all risks.
Brain Development Throughout Life
- Brain development continues throughout life, though major changes occur during adolescence.
- Research suggests that feelings of power can have positive effects on brain function.
