The cerebral circulation
This presentation describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands, and the need for tight water and ion homeostasis. Autoregulation is pronounced in the brain, with myogenic, metabolic, and neurogenic mecha...
