    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.
