  • Title: [Response of splenic resistance and capacitance vessels to electrical stimulation of the hypothalamus and reticular formation in cats].
    Author: Savel'ev AK.
    Journal: Fiziol Zh SSSR Im I M Sechenova; 1977 Mar; 63(3):417-28. PubMed ID: 863039.
    Abstract:
    The effect of electrical stimulation of anterior, medial, and posterior hypothalamus and of midbrain RF on the spleen resistance and capacitance vessels was studied in 48 anesthetized cats. The stimulatin of all the structures but the anterior hypothalamus evoked constrictory responses of the resistance vessels and decreased the blood volume in the spleen. Apart from the constriction, the stimulation of the anterior hypothalamus decreased the tonus of both kinds of vessels in some cases. The highest perfusion pressure was observed during the stimulation of anterior hypothalamus while the greatest rise of venous outflow with the briefest latency was found during the stimulation of the midbrain RF.
