[Electrical activity of the medio-basal cells of the hypothalamus of the ewe after estrogen injection].
Single intravenous injections of estradiol benzoate in castrated, progesteron primed ewes, appeared to activate 34% of the cells located in the hypothalamus, namely in infundibular and ventromedial nuclei. 53% of the activated cells exhibited a typical bursting pattern of discharge. The increase in the mean firing rate could be transitory or durable.
