[The study of the somnological aspects of the human acute adaptation to the high-altitude].

The primary reason of neocortex electrogenesis alteration in high-altitude adaptation at the altitude 3000-5600 m above sea level according to the EEG parameters of the night sleep and wakefulness is brain noncompensated superficial hypoxia. The situation becomes worse at the night by reason of apnoe/hypopnoe effects which occur because of muscular atony during slow sleep fall. The compensation these disorders at the expense of hypertensive and cardiorespiratory responses are identified by general mechanisms and individual strategy.
