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.
How do stimulants affect the brain and body? Stimulants, such as dextroamphetamine (Dexedrine Â®, Adderall Â®) and methylphenidate (Ritalin Â®, Concerta Â®), act in the brain on the family of monoamine neurotransmitter systems, which include norepinephrine and dopamine. Stimulants enhance the effects of these chemicals.
