Exploration of those parts of the brain supplied by the posterior cerebral artery
General cortical distribution of posterior cerebral artery
This view demonstrates the distribution of the posterior cerebral artery. On the right nearly the entire course of the artery is visible. On the left most of the cortical branches are cut off. The lentiform nucleus has been removed on the left to demonstrate the internal capsule. A portion of the tip of the left temporal lobe is visible showing the relation of the hippocampus to the inferior horn of the lateral ventricle. The brain stem is sectioned through the mesencephalon at the level of the inferior colliculi. The corpus callosum has been cut in the midline and most of the left portion removed. Note
1 . Cingulate sulcus
2 . Cingulate gyrus
