Neurovascular regulation
The brain is very sensitive to changes in blood flow. Cerebral blood flow is regulated by a 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 (70 - 150 mm Hg) in a healthy brain.
