Regional Brain Blood Flow during Sympathetic Stimulation

Abstract

It has been recognized that blood flow to the brain and other cephalic tissues is under neurogenic control. Controversy exists regarding the extent to which sympathetic stimulation actually modifies brain blood flow. Recently, there has been increased concern (1, 4) regarding the neurogenic influence on the regulation of cerebral blood flow (CBF). The particle distribution or radioactive microsphere method has been utilized by ourselves (3, 8, 9) and others (5, 6, 7) for examining regional distribution of cardiac output or blood flow to the brain, extracranial tissues, and other organs and tissues. The fundamental considerations underlying this approach have been discussed (3, 6, 7, 10) and the method appears to provide a measure of regional or local blood flow.
