Effects of electrical stimulation of the contralateral supraoptic nucleus (SON) on the activity of neurosecretory neurons in the SON were studied in urethane-anesthetized lactating rats. Thirty-one out of 41 oxytocin neurons were excited and only two neurons were inhibited by contralateral SON stimulation. Eight out of 26 vasopressin neurons were excited and 8 were inhibited. These responses were not affected by suckling stimuli. Neither oxytocin nor vasopressin neurons tested were… CONTINUE READING
