[Effect of the hypothalamus and reticular formation on the cerebral cortex in hypoxic brain states].
In anesthetized cats and unanesthetized rabbits, the reticular formation and the posterior hypothalamus were shown to be able to reduce the resistance of cortical vessels thus increasing the blood supply of the brain cortex. This effect decreased after stimulation of the cortex and in conditions of hypoxia, hypercapnia, section of the vagus, chronic circulatory deficit in the myocardium and the brain.
