How the “Little Brain” Fuels Motivation and Addiction

How the "Little Brain" Fuels Motivation and Addiction

Key points First-of-its-kind research shows how the cerebellum modulates dopamine release within the basal ganglia. Motivation and addiction are both fueled by dopamine activation in the basal ganglia’s substantia nigra. Too little dopamine causes Parkinson’s disease. Stimulating the cerebellum may be a new treatment…
