globus pallidus
Quick Summary
The globus pallidus is a nucleus within the basal ganglia, a group of structures deep beneath the cerebral cortex in the brain. The basal ganglia are crucial for processing information related to movement, helping to plan actions, execute habitual movements, and learn new ones.
The globus pallidus is part of the motor circuit and works in conjunction with other basal ganglia nuclei like the caudate nucleus and putamen. It receives input from these structures and, in turn, influences motor control by modulating signals sent back to the cortex via the thalamus. Dysfunction in the basal ganglia, including the globus pallidus, can lead to movement disorders such as Parkinson disease and Huntington disease.12
