Editing Thalamus (section)

=== Blood supply ===
The thalamus derives its blood supply from a number of arteries: the polar artery ([[posterior communicating artery]]), paramedian thalamic-subthalamic arteries, inferolateral (thalamogeniculate) arteries, and [[Posterior cerebral artery#(Posterior) choroidal branches|posterior (medial and lateral) choroidal arteries]].<ref name="Torrico2023">{{Citation |last1=Torrico |first1=Tyler J. |last2=Munakomi |first2=Sunil |title=Neuroanatomy, Thalamus |date=2023 |url=https://www.ncbi.nlm.nih.gov/books/NBK542184/ |work=StatPearls |access-date=2024-10-13 |place=Treasure Island (FL) |publisher=StatPearls Publishing |pmid=31194341}}</ref><ref>{{cite book |last1=Percheron |first1=G. |year=1982 |chapter=The arterial supply of the thalamus |editor1-last=Schaltenbrand |editor2-last=Walker |editor2-first=A.

Some people have the [[artery of Percheron]], which is a rare anatomic variation in which a single arterial trunk arises from the posterior cerebral artery to supply both parts of the thalamus.
