[The role of the paraventricular hypothalamic nuclei in the reaction of the hypophyseo-adrenal cortex system to cold adaptation].
The lesion of paraventricular hypothalamic nuclei (PVN) led to a delay in the development of cold adaptation in white rats, the latter starting with no activation of pituitary-adrenocortical system. After the PVN lesion, corticosteroid response to immobilization was inhibited. The delay in formation of the cold adaptation seems to be due to the changes in the pituitary-adrenocortical system response to the stress after the PVN lesion.
