Anxiety and cerebral blood flow
American Journal of Psychiatry, 1990The relationship between anxiety and cerebral blood flow (CBF) is of considerable clinical and research significance. Although a considerable amount of information is available on mechanisms through which anxiety may influence CBF, this topic has not received much attention in psychiatry.

To establish the accuracy of transcranial Doppler ultrasound (TCD) measures of middle cerebral artery (MCA) cerebral blood flow velocity (CBFV) as a surrogate of cerebral blood flow (CBF) during hypercapnia (HC) and hypocapnia (HO), we examined whether ...

Cerebral blood flow at high altitude.
High Altitude Medicine & Biology, 2014This brief review traces the last 50 years of research related to cerebral blood flow (CBF) in humans exposed to high altitude. The increase in CBF within the first 12 hours at high altitude and its return to near sea level values after 3-5 days of ...

Cerebral Blood Flow in Schizophrenia
Archives of General Psychiatry, 1983To the Editor— The article "Regional Cerebral Blood Flow in Schizophrenia" by Mathew et al (Archives1982;39:1121-1124) deals with one of the major interfaces between the study of cerebral circulation and psychiatric conditions, and constitutes an important contribution to the field. Therefore, it is regretable that we must point out major problems and

Menstruation and cerebral blood flow
Biological Psychiatry, 1989Gender differences in cerebral blood flow (CBF) are known to exist, with women reported to have higher rates of blood flow at the hemispheric level and to have higher regional flow values in frontal, temporal, and parietal, but not occipital, areas (Gur et al. 1982; Mathew et al. 1986).

Regional cerebral blood flow throughout the sleep-wake cycle. An H2(15)O PET study.
Brain : a journal of neurology, 1997To assess dynamic changes in brain function throughout the sleep-wake cycle, CBF was measured with H2(15)O and PET in 37 normal male volunteers: (i) while awake prior to sleep onset; (ii) during Stage 3-4 sleep, i.e.

Caffeine and Cerebral Blood Flow
British Journal of Psychiatry, 1983SummaryTwo groups of normal volunteers had regional cerebral blood flow (rCBF) measured, by the133Xenon inhalation technique, before and 30 minutes after 250 mg or 500 mg caffeine given orally. rCBF was measured in a third group of subjects, twice, at a similar interval under identical laboratory conditions.

Neurology, 1974
An experimental method is described for determining local cerebral blood flow within an area supplied by a major cerebral artery. With the use of anatomic-radiologic correlates, the territories of the anterior and middle cerebral arteries were defined in the rhesus monkey.

Cerebral blood flow, blood volume and oxygen utilization. Normal values and effect of age.
Brain : a journal of neurology, 1990Regional cerebral blood flow (CBF), oxygen extraction ratio (OER), oxygen utilization (CMRO2) and blood volume (CBV) were measured in a group of 34 healthy volunteers (age range 22-82 yrs) using the 15O steady-state inhalation method and positron ...
