摘要: The intracranial arteries are extensively innervated by autonomic nerve fibers (7). Vasoconstriction of these cerebral has been shown to occur either direct stimulation the sympathetic chain (2), intracarotid infusions norepinephrine, or application this substance on pial vessels (10). Vasodilation elicited seventh cranial (1) brain stem (5). Blocking nerves prevents vasoconstriction (3, 9). vasodilation that occurs when arterial blood pressure is lowered blocked with atropine (6).
