In the brain, dopamine functions as a neurotransmitter âa chemical released by nerve cells to send signals to other nerve cells. The brain includes several distinct dopamine systems, one of which plays a major role in reward-motivated behavior.
Each neurotransmitter is associated with particular effects depending on its distribution among the brainâs various functional areas (see Table 1). Dopamine, for example, is highly concentrated in regions that regulate motivation and feelings of reward, and is a strong motivator for drug use. A neurotransmitterâs impact also depends on whether it stimulates or dampens activity of its target neurons. Some drugs primarily affect one neurotransmitter or class of neurotransmitters. For example, prescription opioids and heroin produce effects that are similar to (but more pronounced than) those produced by the neurotransmitters endorphin and enkephalin: increased analgesia, decreased alertness, and slowed respiration.
