[The effect of hypoxia on the function of the hypothalamic neurosecretory system in rats].

Abstract

Adaptation to intense hypoxia occurs owing to activation of vasopressin-synthetizing magnocellular neurons of the hypothalamus' paraventricular nucleus. The stability of the organism resistance against hypoxia seems to result from highly active state of the CRF and CRF/vasopressin-synthetizing neurons of the parvocellular portion of the paraventricular nucleus controlling the pituitary-adrenal axis.
