Supplies the occipital lobe and the inferior portion of temporal lobe. A branch supplies the choroid plexus.

The posterior cerebral arteries arise from the termination of the basilar artery. Major branches course around the midbrain and above the tentorium to supply the occipital lobe as well as the posteroinferior temporal lobe. Perforating arteries from the posterior cerebral arteries supply the midbrain, hypothalamus and inferior thalami. The posterior pericallosal artery are also branches of the posterior cerebral arteries.

Blockage Affects:

Infarctions of the posterior cerebral arteries most commonly affect vision ( occipital lobes ) but also may affect memory ( temporal lobes ), smell ( hippocampus ), emotion ( splenium ) and other midbrain and thalamic function.
