Abstract	Rearrangements of the temporal organization of the EEG pattern wave structure were studied in 68 subjects who stayed in the Pamir Mountains at an altitude of 3600 m above sea level for one month. The rearrangement of the EEG pattern proceeds through the following stages: (a) a drastic increase in the probability of interaction of α components accompanied by a decrease in wave interactions in the θ and Δ ranges during the first day of adaptation; (b) a decrease in the probability of interaction of α components accompanied by an increase in the probability of interaction with θ and Δ components on the seventh to ninth days; (c) an increase in the probability of interaction with α components in the occipital leads and a high probability of interaction of all EEG components with θ components in the temporal and frontal regions on the 14th to 16th days; (d) a second decrease in the probability of interaction with α components accompanied by an increase in the interactions with the θ- and Δ frequency ranges in subjects with medium or low plasticity (groups II and III, respectively) of neurodynamic processes and a normalization of interaction of α components in subjects with high plasticity (group I) on the 21st to 23rd days; and (e) completion of the adaptive rearrangement of the pattern of interactions between EEG components in group I and, partly, group II subjects and a decrease in the probability of interaction with the α components accompanied by an increase in interaction with θ components in group III subjects on the 28th to 30th days of adaptation. The results of the study indicate a higher adaptability to high-altitude hypoxia in subjects from groups I and II compared to those from group III. These factors should be taken into account when selecting specialists for work in the mountains.
