Regulation of the Cerebral Circulation
Annual Review of Physiology, 1981This aspect of the regulation of the cerebral circulation has been under intensive investigation for the past several years. Many uncertainties have been clarified, but a satisfying answer to the important question of what role neurogenic influences play in the physiological regulation of cerebral blood flow (CBF) remains elusive.

Publisher Summary This chapter focuses on some of the clinically relevant factors and challenges that pertain to the control of the human cerebral circulation. Local increases in brain activity such as occur during cognitive tasks, are reliably accompanied by parallel increases in CBF and glucose metabolism that greatly exceed the rate of oxygen ...

The Control of the Cerebral Circulation
JAMA, 1961The cerebral circulation is broadly limited by factors extrinsic to the brain, namely the general arterial blood pressure and the cardiac output. The cerebral blood flow will be maintained until the cardiac output is decreased by more than a third or the blood pressure is lowered to half or less of the normal value.

The Cerebral Circulation [PDF]
, 2016 As in the case of each regional circulation, the cerebral circulation has special characteristics and unparalleled control mechanisms. The brain also holds a particular role, as it lodges the principal centers of the cardiovascular and respiratory control system of the body. In this chapter, the arteries vascularizing the head and neck, i.e.

Adrenomedullin in the cerebral circulation
Peptides, 2001The central nervous system requires an effective autoregulation of cerebral circulation in order to meet the critical and unusual demands of the brain. In addition, cerebral microvessels has a unique feature, the formation of the blood-brain barrier, which contributes to the stability of the brain parenchymal microenvironment. Many factors are known to

The Speed of Cerebral Circulation
New England Journal of Medicine, 1962IN modern civilizations an enormous toll of suffering and death is exacted by local disorders of brain blood flow. Regional hemodynamic failure, with unique rapidity, produces anoxic devastation in cerebral tissue. The paralyzed neuronal function is reflected clinically as a stroke.

Cerebral circulation and metabolism
Journal of Neurosurgery, 1984✓ Recent developments in the field of cerebral circulation and metabolism are reviewed, with emphasis on circulatory and metabolic events that have a bearing on brain damage incurred in ischemia. The first part of the treatise reviews aspects of cerebral metabolism that provide a link to the coupling of metabolism and blood flow, notably those that ...

Cerebral Circulation Demystified
AACN Advanced Critical Care, 1991Basic anatomic and physiologic concepts related to cerebral circulation are summarized. The arterial blood supply is traced from its origins to the major divisions of anterior and posterior circulation. The circle of Willis, the major arterial vessels and territories, and the peculiarities of the cerebral venous circulation are discussed.

Cerebral circulation and sleep
Sleep Medicine Reviews, 2002Already Aristoteles discussed on restorative functions of sleep (cf. [1]). BorbeÂly [2] was the ®rst to show that the restorative function of sleep correlates to a reduction of homeostatic pressure built up during the day that can be assessed by the slow wave activity of the sleep electroencephalogram (EEG).

Pharmacological Control Of The Cerebral Circulation
Annual Review of Pharmacology and Toxicology, 1991This review is about control of a physiological variable; what that variable's function is and how it is regulated must be discussed first to establish a rational basis for its controL The reader is referred to some excellent recent reviews on regulation of cerebral blood flow (CBF)1 (1-3).
