Regional Cerebral Blood Flow in Aphasia
Archives of Neurology, 1978Regional cerebral blood flow (rCBF) was studied in 13 aphasic patients with left hemisphere lesions, using the intracarotid xenon 133 injection method and a 254-detector gamma camera system. The rCBF was measured during rest and during various function tests, including a simple speech test.

REGIONAL CEREBRAL BLOOD FLOW IN NEUROPSYCHOLOGY
Neuropsychologia, 1986Measurements of regional cerebral blood flow (rCBF) provide information about the metabolic and functional level of the cortex. Different techniques for measurement of rCBF are described and their potentials and limitations are outlined. Typical results from measurements in normals during performance of mental tasks are shown and as well as clinical ...

Regional Cerebral Blood Flow in Schizophrenia
Archives of General Psychiatry, 1982Regional cerebral blood flow (rCBF) was measured via xenon133 inhalation technique in 23 patients with schizophrenia and 18 age- and sex-matched controls. The mean blood flow to both hemispheres was found to be lower for the patients. The patients and their controls did not differ on interhemispheric differences in blood flow. There were no differences

Personality and Regional Cerebral Blood Flow
British Journal of Psychiatry, 1984SummaryThe extraversion–introversion dimension of personality is believed to have an inverse relationship with cortical arousal. Brain capillary perfusion is a well established index of brain function and arousal. Regional cerebral blood flow was measured in 51 right-handed females whose personality structure was examined with the Eysenck Personality ...

Hormones and regional brain blood flow
Pharmacology Biochemistry and Behavior, 1976Acute effects of the hormones, estradiol-17beta and alphaMSH, and of neonatal pretreatment with alphaMSH on the flow of blood to regions of the brains of conscious adult rats have been determined with an indicator distribution technique. As previously reported, flows were reduced in most areas within 10 min after intravenous administration of alphaMSH;

Regional Coronary Blood Flow in Ponies
American Journal of Veterinary Research, 1976SUMMARY Regional coronary blood flow was measured by injecting radioactive microspheres (15 μm ± 5 in diameter) into the left atrium of anesthetized ponies with surgically prepared open thorax before and during occlusion of the coronary arteries. The normal blood flow to the myocardium of the interventricular septum and the left ventricular wall were ...

Regional Renal Blood Flow in Ewes
American Journal of Veterinary Research, 1981SUMMARY Regional blood flow to the kidneys was measured in 6 ewes by injecting carbonized microspheres (15 μm ± 5) labeled with 85Sr into the left ventricle. There was no significant (P > 0.25) difference in the mean arterial pressure before and after injection of the microspheres.

The effect of barbiturates on regional blood flows
Canadian Journal of Anesthesia/Journal canadien d'anesthésie, 1969The intravenous administration of sodium pentobarbital to dogs is associated with a decrease in cardiac contractile force and arterial blood pressure. The latter appears to be due to vasodilatation in major vascular beds, rather than primarily to cardiac depression. Indeed, in most animals cardiac output increases, presumably as a function of increased

The Determinants of Regional Myocardial Blood Flow
1977It is presumed that a region of myocardium does not always have the same blood flow. The purpose of this communication is to examine those factors which are determinants for changing regional flow. We have divided the determinants into three types. Those affecting a regional variation in blood flow which has a random distribution and a cyclic character

Microsphere maps of regional blood flow and regional ventilation
Journal of Applied Physiology, 2007Systematically mapped samples cut from lungs previously labeled with intravascular and aerosol microspheres can be used to create high-resolution maps of regional perfusion and regional ventilation. With multiple radioactive or fluorescent microsphere labels available, this methodology can compare regional flow responses to different interventions ...
