The connections of the subfornical organ to a defined population of hypothalamic neurons have been explored with extracellular recording methods in the rat. Electrical stimulation in the subfornical organ has a predominantly excitatory action on a majority of oxytocin and vasopressin-secreting neurosecretory neurons in the supraoptic and paraventricular nuclei. Subfornical organ stimulation also enhances the excitability of paraventricular nucleus neurons that project to the median eminence, and to the dorsomedial medulla. These observations provide initial evidence of functional connectivity of subfornical organ neurons with other hypothalamic cells that are engaged in central regulation of pituitary secretions and autonomic activities.
利用细胞外记录方法，在大鼠中探究了穹窿下器与特定下丘脑神经元群体之间的联系。穹窿下器的电刺激对视上核和室旁核中大多数分泌催产素和血管加压素的神经分泌神经元主要起兴奋作用。穹窿下器刺激还增强了投射到正中隆起和延髓背内侧的室旁核神经元的兴奋性。这些观察结果为穹窿下器神经元与其他下丘脑细胞的功能连接提供了初步证据，这些下丘脑细胞参与垂体分泌和自主活动的中枢调节。
