What is dopamine?

What is dopamine?

• A. A hormone produced by the liver
• B. A chemical released in the brain that can create feelings of pleasure and reinforce drug use
• C. A type of vitamin
• D. A protein in the blood

Answer: (B)

Dopamine is a neurotransmitter in the brain that helps regulate reward, motivation, and movement. When you experience something rewarding, dopamine is released in brain circuits associated with pleasure, especially in the mesolimbic pathway. Drugs can boost dopamine levels, producing feelings of pleasure and reinforcing the behavior, which makes you more likely to repeat drug use. That’s why the statement describing dopamine as a chemical released in the brain that can create feelings of pleasure and reinforce drug use is the best answer. It isn’t a hormone produced by the liver, a vitamin, or a protein in the blood.
