ADAPTIVE-COMPENSATORY RECONSTRUCTIONS OF HUMAN CORTICAL BIOELECTRICALACTIVITY INTERHEMISPHERIC INTERACTION IN THE CASES WITH BRAIN-STEM LESIONS

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