[The multicomponent composition of the EEG alpha-band in schizophrenic patients].
The functional characteristics of the frequency components ofalpharhythm was studied in schizophrenic patients. The frequency components of the alpha-range EEG were elicited by spectral analysis with FFT-transform. In 80% cases of the patients, the power spectra EEG have multimodal distribution in alpha-range. Spectral analysis from the left and right occipital leads have revealed multimodality in spectral EEG in 20 out of 25 patients. The hyperventilation test in the patients revealed a decreased multimodality and increased unimodality.
