A,The lateral surface of the left cerebral hemisphere, showing the areas suppliedby the cerebral arteries. B,The medial surface of the left cerebral hemisphere,showing the areas supplied by the cerebral arteries. In these figures the areasupplied by the anterior cerebral artery is coloured blue, that by the middle
cerebral artery pink and that by the posterior cerebral artery is yellow.

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.
