The Reward Circuit: How the Brain Responds to Natural Rewards and Drugs

Learn about the limbic system and the biochemical processes that allow this key brain region to process rewards.

The limbic system is activated by healthy, life-sustaining activities such as eating and socializing—but it is also activated by drugs of abuse, which is why they can hijack this circuit and lead to a compulsive cycle of drug use and, in many cases, addiction.
