Abstract
An attempt was made to reveal the mechanisms of adaptation of the human brain to fractional hypoxic load. With this in mind, the dynamics of spontaneous EEG was studied in a 10% hypoxic test performed before and after a course of normobaric hypoxic training. It was shown that under acute hypoxic conditions, the electrical activity of the brain is switched from the α-range frequencies to the generation of medium-amplitude slow-wave oscillations predominantly of the Δ range. This condition of electrogenesis is of a stable character and does not change upon external photostimulation. The training course of hypoxic therapy increases the EEG changes that are revealed. The switch to the generation of slow-wave medium-amplitude oscillations is likely to reflect the adaptation changes.
