  • Abstract
  • Look Inside

Cerebral circulation is regulated by complex mechanisms that allow the brain to regulate its own blood supply. The major factors that regulate cerebral blood flow are classified into neural activity, arterial pressure (autoregu-lation), and neurogenic factors. Dilator responses of the cerebral arteries, that are mediated by nitiric oxide and potassium channels, play an important role in such regulatory mechanisms of cerebral circulation. Cerebral ische-mia alters the reactivity of the cerebral arteries, i. e. vasomotor paralysis, and thereby produces marked deteriora-tion of cerebral blood flow regulation.
