title: [The influence of bulbus olfactorius at the reticular neurons of bulbar respiratory center in hypoxia].
abstract: Under conditions of oxygen deficiency the influence of electrical stimulation of bulbus olfactorius on the impulse activity of reticular neurons of bulbar respiratory center was studied. Under conditions ofnormoxia both activation and inhibition of impulse activity of bulbar respiratory neurons are observed with a predominance of stimulating action. The changes in the dynamic of hypoxia had phase character. At the initial stage of oxygen deficiency (4000-5000 m altitude), during hypoxic activation, the stimulating action of bulbus olfactorius is less expressed than under the conditions ofnormoxia. At the second stage ofhypoxia (7500-8000 m altitude) the stimulating influence of this nucleus was significant.
