Index of Terms

Amygdala

Part of the limbic system, the amygdala is the part of the brain responsible for processing emotions such as fear, anger, and sadness. In The Teenage Brain, Jensen reveals that the amygdala in adolescents is particularly sensitive and reactive to hormones. Consequently, the behavior of teenagers is often driven by intense emotions.

Brain Plasticity

This term describes the capacity of the brain to be molded by information and experiences. Teenagers display a high degree of brain plasticity, making adolescence an optimal time for learning. However, Jensen also explains that neuroplasticity makes teenagers more vulnerable to addiction, and hence is an important component of her theme of Supporting Healthy Brain Development During Adolescence.

Dopamine

As a brain chemical and a hormone, dopamine is central to the brain’s reward circuitry. Humans release dopamine when anticipating a pleasurable experience. Jensen explains that the sense of reward teenagers feel when dopamine is released is greater than that experienced by adults. As a result, adolescents are more likely to seek out new experiences and exhibit risky behavior in order to feel a dopamine “rush.”
