Abstract

The subject of the study is the involvement of reticular neurons (RN) of the bulbar respiratory center in respiration under conditions of hypobaric hypoxia. Such conditions were created in a laboratory altitude chamber and corresponded to a “lift” up to 8000 m altitude. At the beginning of such a “lift”, at pressure corresponding to an altitude of 4000–5000 m, a decrease in the PO2in the inspired air to 98–85 mm Hg resulted an increasing impulse activity of neurons. Within a phase of extreme hypoxia, at an “altitude” of 7500 to 8000 m (PO2= 64–58 mm Hg), considerable suppression of the activity of bulbar RN is observed. Impulse activity of RN in different discharge frequency at different stages of hypoxia has demonstrated considerable specificity.
