Abstract

Analysis of the intra- and interhemispheric EEG coherence in the dynamics of coma regress and its comparison with the clinical stages of postcomatose recovery period revealed both specific interhemispheric rearrangements of the structure of intercentral functional relations, which developed in parallel with the recovery at first of the visual, and then speech functions, and the adaptive-compensatory changes in activity of the regulatory systems, which provide the recovery of mental functions. It is emphasized that the interhemispheric EEG coherence asymmetry, its character and dynamics are significant for formation of neurophysiological mechanisms of consciousness and the course of compensatory processes under the extreme conditions.
