the basal ganglia

The basal ganglia are a group of structures in the brain that play a vital role in coordinating movement and controlling various motor functions. They help regulate voluntary movements, learning habits, and routine actions. By processing information from the cerebral cortex and other areas, the basal ganglia facilitate smooth and purposeful movements while inhibiting unwanted ones. They are also involved in reward processing and decision-making. Dysfunction in the basal ganglia is associated with several neurological disorders, including Parkinson's disease and Huntington's disease, which can affect movement and behavior.
