  5. Dopamine • Is a reinforcing neurotransmitter • Relays a message and makes us feel good (so we will continue to do this) • Eat, drink, sex • It is not the only feel good transmitter – acetylcholine, serotonin, and others.

  6. Why do some drugs make us feel good? • Certain drugs increase the amount of dopamine (or other reinforcing neurotransmitter) and/or prevents re-uptake. • Leaves more dopamine floating around in the brain synapses and gives us a “high” feeling.
