摘要：

Extracellular antidromic potentials were recorded form the paraventricular nucleus of the ovariectomized female rat hypothalamus following electrical stimulation of the neurohypophysis. Effects of estrogen-treatment were investigated after classifying the antidromically identified cells into tonically-firing, physically-firing or silent groups according to their patterns of spontaneous discharge. Estrogen significantly decreased the antidromic threshold and shortened the refractory period as well as the antidromic spike latency in the tonic-firing cells. Estrogen selectively and directly excited the tonically-firing, presumably oxytocinergic cells.
