Explain the concept of cerebral autoregulation
Cerebral autoregulation is a steady-state cerebral blood flow that increases or decreases at rest and during exercise, as Q, the blood flow to the brain, increases or decrease. This regulates cerebral blood flow at a relatively constant flow over a wide range of mean arterial blood pressures. This ability to regulate the flow by altering cerebral vascular resistance over such a wide range of pressures is unique to the brain. All blood vessels of the body have an intrinsic myogenic stretch-contraction property, which is the major mechanistic component of cerebral autoregulation. However, the cerebral autoregulation's greater capacity to autoregulate the brain's blood flow over the wide range of arterial pressures compared with that of the heart, kidney, and other organ beds gives the cerebral circulation its uniqueness.
