[Adaptation to short-term acute hypoxia as a factor in enhancing resistance].
The responses of cortical neurons to multiple short-term hypoxic influences were studied in immobilised cats. ARs were recorded. To produce hypoxia, artificial respiration was switched off for a period of 3-5 min every 60-90 min. Cortical neurons, hypothalamus, cerebellum were shown to increase their tolerance to oxygen deficiency. There was a significant (P = 0.05) increase in the duration of background impulse activity at the 2nd and 3rd exposures to hypoxia. Metabolic rearrangements maintaining neuron electrogenesis, seem to be of great importance in this process.
