Neurosurgery Clinics of North America, 1994
An intricate relationship normally exists between cerebral metabolism and energy substrate supply because of the brain's high substrate demand and limited storage capacity. In head-injured patients, this balance can be disrupted. The brain parenchyma directly involved by the injury is hypometabolic in respect to glucose and oxygen, whereas peri-injury ...

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 ...

On Cerebral Metabolism and Aphasia
Archives of Neurology, 1989To the Editor. —Metter et al1and Kempler et al2recently characterized the regional cerebral metabolic profiles of the perisylvian aphasias, strictly using the Western Aphasia Battery3classification scheme. For illuminating the physiologic processes of neurolinguistic disturbances, this is unsatisfactory, since the Western Aphasia Battery uses ...

Anesthetics and cerebral metabolism
Current Opinion in Anaesthesiology, 2004This review focuses on the utilization of the effects of general anesthetics on cerebral metabolism as revealed by imaging for therapeutic and preventive purposes, for understanding mechanisms of anesthetic action, and for elucidating mechanisms of cerebral processing in humans.General anesthetics suppress cerebral metabolism significantly. This effect

Cerebral metabolism in hepatic insufficiency
The American Journal of Medicine, 1956S TUDIES dealing with neurologic disturbances associated with hepatic insufficiency have been confined chiefly to attempts at identifying the neurotoxic substance or substances responsible for the condition. For the most part, attention has been directed to the concentration of ammonia and other nitrogenous or sulfur-containing compounds in the ...

Chronic ketosis and cerebral metabolism
Annals of Neurology, 1978AbstractThe effects of chronic ketosis on cerebral metabolism were determined in adult rats maintained on a high ‐fat diet for approximately three weeks and compared to a control group of animals. The fat‐fed rats had statistically significantly lower blood glucose concentrations and higher blood β‐hydroxybutyrate and acetoacetate concentrations ...

Glucose is the main substrate for energy metabolism of the brain, and the regional cerebral metabolic rate is directly related to regional brain activity. Therefore, the measurement of regional glucose metabolism is of great importance for the assessment of regional normal function and of pathological changes.

Cerebral metabolism of oxidized ascorbate
Brain Research, 1993The brain has a high level of ascorbic acid which is thought to act as a reducing agent, e.g. in protecting tissues against oxidative stress. The mechanism by which ascorbate is maintained in the useful, reduced state in the CNS is evaluated herein. Cerebrum from rat or calf was minced and homogenized in buffer.

THE INFLUENCE OF THE THYROID ON CEREBRAL METABOLISM*
Endocrinology, 1951THE changes in mental activity associated with abnormal thyroid states have usually been explained on the basis of alterations in cerebral metabolism due directly to local excess or deficiency of the thyroid hormone. Such reasoning has received a certain amount of experimental support, if only by analogy. McEachern (1935) has demonstrated a significant
