This Lecture: Shift your attention from the nature of addiction to the nature of drugs. Here you'll delve into the process of neurochemical transmission and see how drugs mimic this activity by binding to neural receptors. This process is responsible for everything from a drug's physical and psychological effects to its potency. The Course: Addiction touches us all. What happens when your brain is on drugs? Discover the neural mechanisms that underlie the behaviors of addiction, and see how drugs and activities like gambling can hijack the brain and lead to behavioral problems. Understanding addiction can motivate an addict to seek treatment, and can lead loved ones to see the addict in a new way. All Lectures: 1. Addiction 101 2.
