[Vascular reactivity changes in chronic emotional stress of hypothalamic origin].
The vessels of rabbits undergoing a long irritation of the negative emotional zones of the hypothalamus have shown a tendency to increase a constrictive reaction in response to the quantitatively dozed electrostimulation of the vessel walls. This is expressed in the decrease of the range of the stimulation parametres which cause the weakening reaction during 10 days of emotional stress, and in showing only a constrictory reaction to all the parameters of stimulation during a 4-month stress.
