The Influence of Sympathetic Nervous Activity on Cerebral Blood Flow
Abstract
The effect on the cerebral blood flow (CBF) of stimulation of the cervical sympathetic nerve trunk and of intracarotid infusion of levarterenol was explored in anesthetized baboons at varying levels of arterial carbon dioxide pressure. Sympathetic stimulation reduced CBF, and this reduction was more pronounced during hypercapnia; levarterenol reduced CBF by 17% during hypercapnia. On morphological grounds and from physiological data it is argued that there is a dual control of the cerebral circulation—the extraparenchymal vessels being influenced by the sympathetic nervous system, while the intraparenchymal vessels are under local intrinsic metabolic regulation. The pial vessels are possibly influenced by both systems.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
