Which neurotransmitters show changes in the limbic system during adolescence?

• A. Acetylcholine and GABA
• B. Norepinephrine and GABA
• C. Glutamate and GABA
• D. Dopamine and serotonin

Answer: (D)

The limbic system’s changes in adolescence are driven mostly by dopamine and serotonin, which govern reward processing and mood regulation in this brain region. Dopamine in the mesolimbic pathway (including the nucleus accumbens) becomes more responsive to rewards during adolescence, making rewards feel more salient and boosting sensation seeking and risk-taking. Serotonin helps regulate mood, anxiety, and impulse control, and its shifts during this period contribute to the emotional variability teens often show. The combination of heightened dopaminergic reward signaling with serotonergic mood regulation occurs while the prefrontal regions that support planning and impulse control are still maturing, amplifying these limbic-driven changes. So, dopamine and serotonin are the neurotransmitters most closely linked to limbic system changes in adolescence.
