[The reflection of the adaptive restructurings of the human brain in disordered cerebral functions in the parameters of interhemispheric asymmetry in EEG coherence].

In this work was studied a hemispheric specificity of the human brain in a realization of adaptive-compensatory reactions of the CNS. The interhemispheric correlation of EEG coherence functions of the left and the right hemispheres was computed in patients with brain focal lesions in early postsurgery period after an extraction of the medially-located tumor or in far-off time after a hard brain injury (i.e. at different stages of cerebral compensation). The observed peculiarities of changes of the interhemispheric biopotential relations revealed the dynamic character of preferable switching on the right or the left hemisphere in a formation of adaptive-compensatory brain reactions. The specificity of this switching depended on the stage of the pathologic process and reflected the degree of consciousness disturbance.
