title: [Effect of estradiol on the spontaneous activity of individual neurons in the arcuate area of the hypothalamus at different stages of the estrus cycle in rats].
abstract: Microiontophoretic application of estradiol into the arcuate region of the hypothalamus increased the activity of single neurons in the majority of experiments. This reaction was more pronounced at the stage of dietrus-1 and diestrus-2 than during proestrus. It is supposed that the changes in the prevailing reactions of the arcuate region neurons to the estradiol administration in the course of the estrual cycle were determined by the level of the endogenous estrogens and gonadotropins of the hypophysis in the peripheral blood.
