Which neurotransmitter is commonly linked to feelings of pleasure?

• A. Dopamine
• B. GABA
• C. Norepinephrine
• D. Serotonin

Answer: (A)

Dopamine is central to reward, motivation, and the experience of pleasure. When a person anticipates or receives a rewarding outcome, dopamine is released in the brain’s reward pathways (especially the mesolimbic pathway), producing pleasurable feelings and reinforcing the behavior that led to the reward. Other neurotransmitters have important functions—GABA inhibits neural activity, norepinephrine is tied to arousal and focus, and serotonin influences mood and well‑being—but they do not align as directly with the hedonic pleasure signal as dopamine does. So dopamine best explains why certain activities feel rewarding and why we’re motivated to repeat them.
