Arterial supply to the internal capsule and parts of the basal ganglia of the leftcerebral hemisphere. The outer layers of the hemisphere have been removed toreveal these structures. The putamen and globus pallidus are displaced downwardsto display the internal capsule. Territory supplied by branches of the anterior and

middle cerebral arteries is shown in red. Territory supplied by the anteriorchoroidal arter is shown in reen.
