The globus pallidus is a triangular-shaped, subcortical structure of the brain. It is located below the cerebral cortex, medial to the putamen.
The globus pallidus is part of a large group of subcortical nuclei called basal ganglia. It can be functionally divided into two main parts:
- Medial (internal) segment
- Lateral (external) segment
Together with the putamen, it comprises the larger lentiform (lenticular) nucleus that lies beneath the insula. The lentiform nucleus and caudate form the corpus striatum, a critical component of the basal ganglia.
The main function of the globus pallidus is movement control. More specifically, it regulates conscious and voluntary movement. In addition, globus pallidus connects to cortical areas that support various functions, including motivation and cognition.
