Thirteen neurons in the subfornical organ (SFO) were antidromically activated by electrical stimulation of the paraventricular nucleus (PVN) in the rat. The activity of these identified SFO neurons was excited by intravenous injection of angiotensin II (AII). Electrical stimulation of the SFO produced orthodromic excitation (40%) and inhibition (40%) of the activity of putative vasopressin (VP)-secreting PVN neurons. These results suggest that circulating AII sensitive SFO neurons with efferent projections to the PVN have both excitatory and inhibitory influences on the activity of putative VP-secreting neurons in the PVN.
电刺激大鼠室旁核（PVN）可逆向激活穹窿下器（SFO）中的13个神经元。静脉注射血管紧张素II（AII）可兴奋这些已鉴定的SFO神经元的活动。电刺激SFO可对假定的分泌加压素（VP）的PVN神经元活动产生顺向兴奋（40%）和抑制（40%）。这些结果表明，循环中的AII敏感的、向PVN发出传出投射的SFO神经元对PVN中假定的分泌VP的神经元活动具有兴奋和抑制作用。
