Clinical significanceThe functions of the thalamus and midbrain include the regulation of consciousness, sleep and alertness. Occlusion of the artery of Percheron, for example by a clot, could result in a posterior circulation infarct impairing structures on both sides of the brain. This can produce a bizarre disturbance such as sleep from which the patient cannot be awakened.[1] HistoryThe artery of Percheron was first described in 1973 by the French medical scientist Gerard Percheron.[2][3][4] References1. ^{{cite web |url=http://well.blogs.nytimes.com/2012/02/03/think-like-a-doctor-sleeping-wife-solved/ |first=Lisa |last=Sanders |title=Think Like a Doctor: Sleeping Wife Solved! |date=February 3, 2012 |publisher=The New York Times}} {{Arteries of head and neck}}{{circulatory-stub}}2. ^{{cite journal |author=Percheron G |title=The anatomy of the arterial supply of the human thalamus and its use for the interpretation of the thalamic vascular pathology |journal=Zeitschrift für Neurologie |volume=205 |issue=1 |pages=1–13 |date=August 1973 |pmid=4126735 |doi=10.1007/BF00315956}} 3. ^{{cite journal |vauthors=Agarwal N, Chaudhari A, Hansberry DR, Prestigiacomo CJ |title=Redefining thalamic vascularization vicariously through gerald percheron: a historical vignette |journal=World Neurosurgery |volume=81 |issue=1 |pages=198–201 |date=January 2014 |pmid=23314026 |doi=10.1016/j.wneu.2013.01.030}} 4. ^{{Cite book|title=The Upper Brainstem in the Human|last=IV.
