["Forced normalization" EEG phenomenon and several mechanisms of psychopathologic symptoms in epileptic patients].

Some electrophysiological correlations of periodically exacerbating psychopathological manifestations in epilepsy are discussed. It was established that in phenomenon of a "forced normalization" of the EEG deep structures of the lymbic system may show active foci of epileptical bioelectrical activity. It is suggested that such pictures of bioelectrical activity in the different brain structures are formed as a result of dissociated inhibitory influences of the brain stem. The necessity of a stereoelectroencephalographic study in this group of patients is emphasized in order to assess the possibilities of a successful surgical operation.
