title: [The reaction of the respiratory neurons of the medulla oblongata to stimulation of the amygdaloid complex nuclei in hypoxia].
abstract: Under atmospheric pressure, stimulation of amygdala induced an activating effect on the medullary respiratory and reticular neurons. At the initial stage of hypoxia (altitude 4000-5000 metres), against the background of hypoxic activation of the firing rate, facilitating influence of tetanic stimulation of the amygdala was lesser even though prevailing over its inhibiting action. At the maximal altitude (7500-8000 m), against the background of hypoxic suppression of unit activity, the stimulation of amygdala exerted mainly an activating effect. The response was particularly obvious in the neurons with low spontaneous activity.
