Reflection: For this project, we had to pick a condition that can affect the function and the physiology of the brain. We decided to focus on drug addiction. This is a big epidemic in the US with opioids and heroin. I learned that drugs flow to your reward system so that your body wants to intake more. Drugs harm the Limbic System, the brain stem, and the Cerebral Cortex. During our research, we also found ways to stop drug addiction.
