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 ...

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 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.

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).

Different investigators seem to have obtained different results from the intravenous injection and local application of solution of pituitary, U. S. P. Dixon and Halliburton,1in brain perfusion experiments on dogs, found that pituitary at first constricted and then dilated cerebral arteries.

Investigations by Fog1and Forbes, Nason and Wortman2have demonstrated that the pial arteries react to a fall in blood pressure by dilatation. This reaction was shown to be independent of the way in which the fall in pressure was produced. It was noted also by these authors that the same arteries react to a rise in blood pressure by constriction, but no

Since the cerebral circulation is dominated by the blood vessels of the pia mater, their activity is of major importance to the brain. That these vessels are richly supplied with nerves can no longer be questioned. Convincing data are available from both the histologic and the physiologic points of view.

In this series of investigations on cerebral circulation many of the data have been obtained by using a special method of measuring arteries in the pia through a cranial window. In order to interpret these findings correctly, it is necessary to recognize a number of factors which may affect the results. Aside from the one experimental factor— purposely

It is a common opinion among physiologists that the cerebral blood vessels do not possess effective vasomotor nerve control. The strongest evidence on which this opinion rests has been brought forward by a number of English physiologists, notably Roy and Sherrington,1Bayliss and Leonard Hill,2Hill and Macleod3and Florey.4Several Germans5have also ...

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 ...
