[Nature of "congestive" stimulation in emotional stress as a basis of cardiovascular disorders].

The role of the limbicoreticular structures of the brain in the mechanism of cardiovascular reactions to the electric stimulation of the emotiogenic zones of the ventromedial hypothalamus has been described in the paper. It is shown that during emotional reactions the sensitivity of certain neurons of the reticular formation of medulla oblongata to chemical stimulants and of the hypothalamus to neuromediators is changed. The importance of certain oligopeptides (angiotensin II, bradykinin, renin, and delta-sheep-producing peptide) in the genesis of cardiovascular disorders observed in the stimulation of the emotiogenic zones of the ventromedial hypothalamus has been elucidated.
