In the human setting, it has been shown that acute increase in the concentration of ketone bodies by infusion of β-hydroxybutyrate increased the cerebral blood flow (CBF) without affecting the overall cerebral metabolic activity. The mechanism by wh

Background and Purpose — It has previously been shown that activation will increase cerebral blood flow (CBF) and cerebral glucose uptake (CMR glc ) in excess of cerebral oxygen uptake (CMRO 2 ). Our purpose was to investigate the influence of β-a

Quantification of regional cerebral glucose metabolism (CMRglc) using positron emission tomography and 18F-fluorodeoxyglucose (PET-FDG) requires knowledge of the correction factor between FDG and glucose net clearance, the FDG lumped constant (LC). B

In the clinical setting it has been shown that activation will increase cerebral glucose uptake in excess of cerebral oxygen uptake. To study this phenomenon further, this study presents an experimental setup that enables precise determination of the

We studied a 7.5 French Opticat fiberoptic catheter/Oximetrix computer system as a tool for continuous monitoring of oxygen saturation of jugular venous blood. Eight healthy volunteers had a catheter placed with the tip in the bulb of the right inter

1. 1. In order to find a correlation between the thermal conditions in bed and the quality of sleep, 5 young, healthy persons were tested in a thermal climate chamber. 2. 2. The sleep of each person was thoroughly monitored during 5 nights (stages I

The Kety–Schmidt technique can be regarded as the reference method for measurement of global average cerebral blood flow (average CBF) and global average cerebral metabolic rate of oxygen (average CMRO2). However, in the practical application of th

This is the first report on the distribution of regional cerebral blood flow (rCBF) changes during stage-1 sleep or somnolence. Two hypotheses were tested: (A) that rCBF differed between the awake relaxed state and stage-1 sleep, (B) that hypnagogic

The effect of acute and long-term treatment with propranolol on cerebral blood flow (CBF) and the cerebral metabolic rate of oxygen (CMRO2) has been studied in 8 young healthy volunteers. CBF was measured by 133Xe-inhalation and single photon emissio

The lumped constant defined as the conversion factor between the net uptake of fluoro-2-deoxy-D-glucose (FDG) and glucose was calculated from global CMRglc and from positron emission tomography (PET) using FDG as tracer (CMRFDG). Fifteen healthy, nor
