The globus pallidus is a structure located deep within the brain, specifically part of the basal ganglia. It plays a crucial role in regulating voluntary movement and coordinating motor control. The globus pallidus is divided into two segments: the internal and external segments, each with distinct functions in processing information related to movement. This brain region receives input from various areas, including the cerebral cortex and striatum, and sends output to the thalamus. By modulating signals, the globus pallidus helps fine-tune motor activity, ensuring smooth and controlled movements. Dysfunction in this area can lead to movement disorders, such as Parkinson's disease.
