The brain is very sensitive to changes in blood flow. Cerebral blood flow is maintained and regulated by a homeostatic process called autoregulation. Cerebral blood flow is maintained at approximately 40-70 ml per minute for every 100 g of brain tissue, which occurs over a wide range of arterial blood pressures (~60 - 160 mm Hg) in a healthy brain. To maintain constant cerebral blood flow, several homeostatic mechanisms converge to maintain a balance between vasoconstriction and vasodilation, which includes myogenic, neurogenic, metabolic, and endothelial components (Armstead, Anesthesiol Clin. 2016; 34(3): 465–477).
