[Adaptive-compensatory restructurings of the intrahemispheric interaction of electrical processes in the human brain...

In 50 patients with focal lesions of the brainstem was analysed the postsurgery dynamics of the interhemispheric interaction (by the characteristics of EEG coherence). Was shown a specific participation of the left and the right hemispheres in a realization of postoperative compensatory brain reactions. In survived patients in early terms after surgery the phase was revealed in which coherence in the left hemisphere exceeded that in the right one and the difference being significant for the frontal areas. This phenomenon reflected higher reactivity of the dominant hemisphere in a realization of the adaptive reactions of the CNS. Right hemispheric EEG coherence in general had lower values and was more inert. It dominated under the conditions when only vegetative regulation remained before the lethal exit.
