Dopamine
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.

  • Leaves more dopamine floating around in the brain synapses and gives us a “high” feeling.
