RESUMO
In anesthetized cats, spontaneous activity was recorded in neurons of the anterior, supraoptic, lateral, ventro-medial and posterior nuclei of the hypothalamus under conditions of oxygen deficit induced by the blood loss or discontinuation of artificial respiration. Phases of activation and suppression of electric activity of different hypothalamic nuclei did not develop simultaneously. At the onset of hypoxia development of activation involved the anterior areas and then propagated to the posterior hypothalamic structures. The supraoptic nucleus seems to play a triggering role in the development of compensatory-adaptive response in the hypothalamus under the effect of stress.
