| Summary: | Association between cerebral blood flow and higher nervous activity in people at different stages of adaptation to the midlands was studied. Investigation were performed before, during and after a three-week stay in the mountains at an altitude of 2100 m, as well as during short-term ups without the physical load on the height of 3900 m. In the initial period of adaptation to hypoxia desynchronization between the nerve processes in the cerebral cortex and brain blood flow was observed. There was an inversion and an increase in the asymmetry of cerebral blood flow in the direction of the dominance of the left hemisphere of the brain. After the three-week stay in the mountains asymmetry of cerebral blood flow was disappeared, blood flow to the brain was reduced, hemispheric symmetry was formed, and blood flow synchronized with the nerve processes in the cerebral cortex again was restored. |
