Cerebral autoregulation is the brain's ability to maintain a relatively constant cerebral blood flow (CBF) over a wide range of mean arterial pressures (roughly 50-150 mmHg) through active adjustment of cerebrovascular resistance.

Good results from multiple authoritative sources. Now reading the most relevant sections in parallel.

Excellent content. Now fetching the image from Miller's Anesthesia (the autoregulation curve diagram) and reading the Barash section and Morgan & Mikhail for mechanisms and clinical details.
