Ageing Research Reviews, 2016
Cerebral circulation is known to be protected by the regulatory function against the hypoperfusion that will affect the cognitive function as a result of brain ischemia and energy failure. The regulatory function includes cerebrovascular autoregulation, chemical control, metabolic control, and neurogenic control, and those compensatory mechanisms can ...

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.

Regulation of the Cerebral Circulation by Arterial Carbon Dioxide.
Comprehensive Physiology, 2019Intact, coordinated, and precisely regulated cerebrovascular responses are required for the maintenance of cerebral metabolic homeostasis, adequate perfusion, oxygen delivery, and acid-base balance during deviations from homeostasis.

Rheology of the Cerebral Circulation
Neurosurgery, 1984Current concepts of brain perfusion focus on the importance of rheological factors in the determination of cerebral blood flow. Blood viscosity, a primary determinant of blood flow, increases as the shear rate (velocity gradient) decreases, thereby impeding cerebral perfusion.

Cerebral Circulation and Resuscitation
Acta Anaesthesiologica Scandinavica, 1968SUMMARYAfter reviewing the literature mainly with a view to elucidate the effect of drugs commonly used in cardiac resuscitation on CBF, attention is drawn to the frequent occurrence of obstruction or stenosis in the extracranial cerebral vessels.

1982
The heart and the brain were undoubtedly recognized by primi-tive man as the most vital of the organs, even though it was not until three hundred years ago that the relationship between them began to be clarified. The pulsations of the brain during life are mentioned in the Smith Papyrus, one of the earliest of medical texts, which was written around ...

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.

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.

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 ...
