Understanding Drug Abuse and Addiction: What Science Says

3: Brain regions and their functions

Brain with the regions that control movement, sensations, vision, coordination, memory, reward, and judgment highlighted

Certain parts of the brain govern specific functions. For example, the cerebellum is involved with coordination; the hippocampus with memory. Nerve cells (neurons) are the basic unit of communication in the brain. Information is relayed from one area of the brain to other areas through complex circuits of interconnected neurons. Information via electrical impulses transmitted from one neuron to many others is done through a process called "neurotransmission."
