Dopamine Levels Increase. All addictive drugs affect brain pathways involving rewardâthat is, the dopamine system in the reward pathway. Within seconds to minutes of entering the body, drugs cause dramatic changes to synapses in the brain. By activating the brain's reward circuitry, drugs deliver a jolt of intense pleasure.
In Activity 1, students learned that drugs change the communication between neurons. However, hands-on classroom investigations of drugsâ effects on the brain are impossible. The following activity is an exercise that students can do to learn more about how a drug, caffeine, affects their body.ne way to affect synaptic transmission is to increase the amount of neurotransmitter released into the synaptic space. Drugs like alcohol, heroin, and nicotine indirectly excite the dopamine-containing neurons in the ventral tegmental area (VTA) so that they produce more action potentials.
