The lateral sulcus (also called Sylvian fissure or lateral fissure) is one of the most prominent features of the human brain - https://en.wikipedia.org/wiki/Lateral_sulcus The superior temporal branch (Fig. 1-8) is usually the strongest cortical branch of the middle cerebral artery and its further continuation in the area of the cortex. - http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100... Having left the Sylvian fissure, it runs towards the middle Suprasylvian sulcus and further to the upper margin of the cerebral hemisphere - the same link The CT scans show a hypodensity primarily affecting the territory of the superior division of the right middle cerebral artery, involving the right frontal lobe above the Sylvian fissure. - https://case.edu/med/neurology/NR/mcasuperior.htm Cette zone du cerveau appelée jonction temporo-pariétale (TPJ) qui se situe à la réunion des lobes temporal and pariétal explique les différences extrêmes d'altruisme d’un individu à l’autre - https://www.santelog.com/actualites/laltruisme-juste-une-que...

peer agreement (net): +1watershed area Explanation: https://www.neurovascularmedicine.com/watershed.php A watershed infarct is a stroke caused by a drop in circulating pressure and or volume that results in critical ischaemia or infarction between territories. Classically between MCA and ACA or MCA and PCA. The actual blood stream blockage/restriction site can be located far away from the infarct. -------------------------------------------------- Note added at 20 hrs (2021-01-17 13:38:15 GMT) -------------------------------------------------- https://www.medscape.com/answers/338385-168939/what-are-wate... Vascular watershed or border-zone infarctions occur at the most distal areas between arterial territories (see the image below). They are believed to be secondary to embolic phenomenon or due to severe hypoperfusion, such as in carotid occlusion or prolonged hypotension. [21, 22] -------------------------------------------------- Note added at 20 hrs (2021-01-17 13:51:51 GMT) -------------------------------------------------- the major arteries supplying the cerebrum are the middle cerebral artery, anterior cerebral artery, and posterior cerebral artery. "Jonctionnel"refers to tissue at the extremities of the regions supplied by these arteries, where one arterial territory meets another. My first reference has an image of watershed areas/border zone (see under Images) -------------------------------------------------- Note added at 20 hrs (2021-01-17 14:00:53 GMT) -------------------------------------------------- https://www.ahajournals.org/doi/full/10.1161/01.str.00001557... -------------------------------------------------- Note added at 20 hrs (2021-01-17 14:02:15 GMT) -------------------------------------------------- Susceptibility of the WS areas is thought to result from their situation of “distal field,” where perfusion pressure is lowest |

INTRODUCTION : Les infarctus cérébraux jonctionnels (ICJ) sont souvent dus à une sténose de l’axe carotidosylvien. Leur physiopathologie est discutée selon leur pattern radiologique entre mécanisme embolique ou hémodynamique. Dans la littérature, les ICJ corticaux (ICJc) seraient préférentiellement emboliques. Les ICJ profonds (ICJp) seraient, quant à eux, d’origine purement hémodynamique.
