Cerebral blood flow changes and its interrelation with neurodynamic processes in adapting to high altitude

The article presents the results of the study of interrelations between hemispheric asymmetry of cerebral blood flow and neurodynamic processes in humans during a three week stay in the mountains at altitude of 2100 meters, and thereafter in plains. It was found that at first in the mountains the cerebral blood flow shifted to the left-brain predominance, at end of the stay, this asymmetry was reduced. Also in the early period of adaptation, desynchronization of links between cerebral blood flow and neural processes was observed, after three weeks they became balanced and more sustainable. As a result of adaptation inter-hemispheric symmetry of cerebral blood flow and its stable link with the character of neurodynamic processes were formed.
