What is one role of the basal ganglia in the brain?

The basal ganglia play a crucial role in controlling voluntary movement. This group of nuclei in the brain is involved in coordinating movement, facilitating smooth and purposeful motor actions, and suppressing unwanted movements. The basal ganglia process information from various cortical areas and help refine motor plans before they are executed. They are essential for motor learning, habit formation, and the execution of learned motor tasks. Dysfunction of the basal ganglia is linked to movement disorders such as Parkinson's disease and Huntington's disease, which further underscores their significance in motor control. Understanding this role helps clarify the importance of the basal ganglia in the overall functioning of the motor system and how disturbances can lead to significant clinical symptoms.
