The putamen is a round structure located deep within the brain, specifically part of the basal ganglia. It plays a crucial role in regulating movements and various aspects of motor control. The putamen works closely with other structures in the basal ganglia, such as the caudate nucleus and globus pallidus, to help coordinate smooth and purposeful movements. In addition to its role in movement, the putamen is also involved in learning and habit formation. It processes information related to rewards and is linked to the brain's dopamine system, which is important for motivation and reinforcement of behaviors.
