We compared the neuropathological consequences of global forebrain ischemia under normothermia versus mild hyperthermia. Twenty-one rats underwent 20 minutes of four-vessel occlusion during which brain temperature was maintained at either 37 degrees C (normothermia, n = 9) or 39 degrees C (hyperthermia, n = 12). Quantitative neuropathological assessment was(More)
The consequences of acute amphetamine administration on the metabolic responsiveness of the cerebral cortex to physiologic activation were studied in normal and infarcted rats. Treated rats received a 4 mg/kg intravenous injection of d-amphetamine 1 hour before unilateral vibrissae stimulation and 2-deoxyglucose study. In nontreated normal rats, metabolic(More)
