ABSTRACT
At the present time there is significant progress in study of the pathogenesis of mental illnesses, in comparison with previous work, carried out using traditional EEG methods. This progress is connected with new methods for analysis of brain functions, including positron emission tomography (PET), functional magnetic resonance imaging (fMRI) and single photon emission tomography (SPET), these being methods of “living brain imaging”. EEG mapping is also regarded as one of these methods. Using this method we have revealed some inter-and intrahemispheric deviations of different EEG rhythms in patients with depression and schizophrenia, characterized (respectively) by predominance either of emotional or cognitive disturbances.
