Stimulation of the ventro-medial nucleus of the hypothalamus induces active constriction of both pre- and post-capillary vessels in the dog's hindlimb. Alpha-adrenolytic agents reduce these responses, indicating that they are mediated by the sympathetic nervous system. Stimulation of the paraventricular nucleus dilates both resistance and capacitance vessels. The present study demonstrates that hypothalamic neurones can control venomotor tone.
刺激下丘脑腹内侧核会引起犬后肢毛细血管前和毛细血管后血管的主动收缩。α-肾上腺素能阻滞剂可减弱这些反应，表明它们是由交感神经系统介导的。刺激室旁核会使阻力血管和容量血管扩张。本研究表明，下丘脑神经元可控制血管舒缩张力。
