The study of interhemispheric bioelectrical asymmetry (IBA) of the brain as a result of pair activity of the hemispheres has shown that in normal subjects IBA was greater in the frontal lobes than in the occipital ones. In patients with injured right hemisphere the asymmetry increased in the occipital lobes. In patients with injured left hemisphere the(More)

The method of evoked potentials was used in acute experiments on cats anesthetized with chloralose-nembutal to study the participation of the cortical associative areas in the recovery of disturbed functions of the brain after experimental injury to projection (somatosensory and visual) areas of the contralateral hemisphere. It was shown that temporal(More)
The gears of the conjugate activity of hemispheres in the presence of damage in one were studied before and after removal of a tumor by using an interhemispheric asymmetry index. On left hemispheric exposure, the index decreased in the anterior brain regions having mainly morphofunctional connections with the activating structures of the stem. The posterior(More)
The effect of ultrasonic neurosurgical instruments on the functional state of the brain and its individual structures was studied to establish the most adequate and the least traumatic method of brain structures extirpation. Cortical zones were destroyed by ultrasound, thermocoagulated or extirpated. Parallel recordings of evoked potentials to single and(More)
In the last decade new facts characterizing the morphological and functional cortical organization of projection and association systems have been obtained in the course of experimental and clinical observations and these have contributed to our understanding of the mechanisms of the reliability of brain activity [1-3, 8]. However, pathways of restoration(More)

The fluctuations of functional brain condition level are evaluated by interhemispheric asymmetry of bioelectric activity power that is a consequence of both hemispheres interplay and involvement of nonspecific brain system in this process. Using neurological examination and electroencephalography, functional CNS condition analysis in patients with chronic(More)
