ESTIMATION OF ADAPTIVE HUMAN BRAIN RECONSTRUCTIONS AT A DISTURBANCE OF THE CEREBRAL FUNCTIONS BY 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 in terhemispheric correlation of EEG coherence functions of the left and the right hemispheres was computed in patients with brain focal lesion s in early postsurgery period after an extraction of the medially--loc ated tumor or in far-off time after a hard brain injury (i. e. at diff erent stages of cerebral compensation). The observed peculiarities of changes of the interhemispheric biopotential relations revealed the dy namic character of preferable switching on the right or the left hemis phere in a formation of adaptive-compensatory brain reactions. The spe cificity of this switching depended on the stage of the pathologic pro cess and reflected the degree of consciousness disturbance.
