title: [The characteristics of the bioelectrical activity of the human brain in lesions of different sections of the corpus callosum].
abstract: This work represents the results of analysis of EEG, its structure and spreading along the cortex in 44 patients with arteriovenous malformations of the corpus callosum. The method of quantitative EEG analysis was used with computation of the spectral power and intercentral coherence. The results gave a possibility of a comparative evaluation of changes in spontaneous cerebral activity after the lesions in different portions of the corpus callosum (anterior, middle, and posterior) and permitted to characterize their contribution into the genesis of EEG. A conclusion is drown that coherence spectra are a significant parameter reflecting intra- and interhemispheric intercentral relations of electrical brain processes. These connections were more deranged after the lesions of the anterior and the middle portions of the corpus callosum than those of the posterior portion.
