Abstract

In the oxygen deficiency conditions we studied the influence of irritation of fornix stimulation on the impulse activity of the reticulary neurons and on the respiration. Phases of hypoxia were the model of experiment. At the initial stage of hypoxia (4000–5000 m higher) the frequency of reticulary neurons was growing. Against this background the facilitating influence of stimulation of fornix was less prominent, though it prevailed over its inhibiting action. At the maximal altitude (7500–8000 m higher) however, the frequency of stimuls was falling, and mainly the facilitating effect of stimulation of fornix was continuing. The rats after being brought back to the normal atmospheric pressure displayed gradual recovery of initial exponents with respect to both the ccof neurons and the reactions to stimulation. Those different reactions of irritation fornix have regulation sense on respiratory neurons
