Cerebral Autoregulation

Cerebral autoregulation is the brain's way of automatically maintaining a stable blood flow despite changes in blood pressure. When blood pressure rises, blood vessels in the brain constrict to prevent too much blood from causing damage. Conversely, if blood pressure drops, these vessels dilate to ensure the brain gets enough oxygen and nutrients. This process keeps the brain's environment steady, protecting it from potential harm caused by fluctuating blood pressure and ensuring consistent brain function.
