Brain Reward System

This presentation gives students a clear and relatable understanding of how the brain’s reward system influences motivation, pleasure, and addiction. Through visual analogies and real-world examples, students learn how neurotransmitters like dopamine, endorphins, and serotonin interact with brain receptors to create feelings of satisfaction. The lesson also explains how drug use hijacks this system, leading to desensitization, downregulation, and long-term changes in brain chemistry. With editable slides, a printable student reference guide, and strong links to prior content on neurotransmitters, this resource is ideal for Counseling & Mental Health I, General Psychology, and Health Science classes focused on behavior and brain health.
