The globus pallidus internus (GPi) is part of the globus pallidus and thus part of the basal ganglia.
Clinical Relevance
In neurosurgery, the globus pallidus internus serves as a target for Deep Brain Stimulation (DBS) for Parkinson's disease1 or in the treatment of dystonia2.
Imaging
The globus pallidus internus can be delineated particularly well on MDEFT sequences3.
