[Characteristics of electroencephalographic changes in hypotensive and hypertensive reactions caused by hypothalamic stimulation].
Electrical activity changes of the cortical and subcortical formations in the hypo- and hypertensive vascular reactions induced by hypothalamus electrical stimulation before and after introduction of monoaminohydroxydase inhibitor, vetrasine, were studied in experiments on urethane-anesthetized rabbits. Hypertensive reaction completely blocked by vetrasine were, while hypotensive hypothalamic reactions remained unchanged. These findings are interpreted of the basis of differences in the neurochemical mechanism of the pressor and depressor hypothalamic reactions.
