Patterns of Fetal Lamb Regional Cerebral Blood Flow during and after Prolonged Hypoxia
… during prolonged intrauterine hypoxia, total and regional cerebral blood flows increase to the same extent without evidence of preferential shunting to critical brainstem or subcortical areas. Neuropathologic studies have indicated relative sparing of these areas during similar animal experimental …

<sup>133</sup>Xe Inhalation Technique: Effect of the Contralateral Contribution on Regional Cerebral Blood Flow Parameters.
The method of estimating regional cerebral blood flow (rCBF), which involves inhalation of the gaseous radioisotope 133Xe, was introduced by Mallett and Veall, and later modified by Obrist, et al. The details of our laboratory arrangement at University Hospital have been previously reported. The …

Neuropsychological Functioning and Regional Cerebral Blood Flow: A Comparison Between Aged Normals and Alzheimer’s Type Dementia.
… the 133 Xenon inhalation method of determining regional cerebral blood flow (rCBF). In addition, correlations between rCBF detectors and Luria-Nebraska localization scales were investigated in order to ascertain possible agreement on focal areas of functional brain tissue loss. Nine subjects …

Longitudinal tracking of neural vascular recovery post microinfarct using multimodal neural platform
… is caused by the obstruction or reduction of blood flow to part of the brain, typically due to the buildup of cholesterol-containing fatty deposits called plaques in an artery or one of its branches. Microinfarcts are a milder form of ischemic stroke with tiny area of tissue damage resulting …

Resting-State Cerebral Perfusion Patterns: An Exploratory Factor Analysis of Single-Photon Emission Computed Tomography Clinical Data
… emission computed tomography (SPECT) regional cerebral blood flow (rCBF) to analyze RS. The omission is critical because SPECT RS networks have a different structure and statistical representation than functional magnetic resonance imaging (fMRI) RS networks. Moreover, recent fMRI …

Predictive utility of neuropsychological measures and single photon emission computed tomography (SPECT) in the classification of cerebral perfusion deficits in dementia of the Alzheimer type (DAT)
… and perfusion deficits, based upon measures of regional cerebral blood flow (rCBF) taken from the single photon emission computed tomography (SPECT) scans of patients suffering from dementia of the Alzheimer type (DAT). The study was designed to determine if DAT patients categorized as having …

CHOLINERGIC CONTRIBUTIONS TO EMOTION REGULATION
… the brain, while significantly increasing tracer flow in limbic compared with non-limbic regions. In Experiment II, behavioral and physiological measures were assessed at baseline and following procaine in 32 healthy controls and 15 patients with bipolar disorder undergoing [15O] PET yielding …

Hypertension, blood pressure, cognition and cerebral blood flow in the cohort of "Men born 1914"
… of carotid arteries, 24-hour ambulatory blood pressure monitoring, regional cerebral blood flow, and cardiovascular risk factors. It is well known that hypertension plays a major etiological role in the development of cerebrovascular disease, ischemic heart disease, and cardiac failure. …

The functional neurophysiological sequelae associated with high frequency dream recallers
… brain reactivity, as well as increased regional cerebral blood flow in areas in the brain associated with dream production. These results are indicative of the existence of a functional neurophysiological trait innate to HRs, while also supporting the premise that apart from a better …

Neurodegenerative Biomarkers in Healthy Elderly - with special reference to the preclinical pattern of biological and cognitive markers for Alzheimer’s disease
… and underwent assessments of EEG activity and regional cerebral blood flow (rCBF) as well as repeated assessments of cognitive function and CSF biomarker levels. The CSF biomarkers were Aβ42, total tau (t-tau) and hyperphosphorylated tau (p-tau). The cognitive testing included among others the …

Neuropsychological functions and association with single photon emission computed tomography (SPECT) in Greek multiple sclerosis patients : efficacy of a computerized cognitive rehabilitation intervention
… impaired RRMS patients (n=31), that underwent regional cerebral blood flow (rCBF) brain SPECT evaluation at baseline, demonstrated greater hypoperfusion rates in several predefined Brodmann areas and lobes of the brain, relative to demographically matched healthy controls according to an …

Cerebral blood flow in the non-human primate : an in vivo model and drug interventions
Cerebral blood flow dynamics is an essential component for preserving cerebral integrity. Cerebral blood flow abnormalities are often seen in patients with central nervous system pathologies such as epilepsy, migraine, Alzheimer's Disease, vascular dementia, stroke, and even HIV/AIDS. There is …
