Abstract

The features and prognostic value of wavelet-synchrony of evoked responses during the listening to realistic stimuli (music) were revealed in the study. Musical passages were selected according the patients’ preferences by their relations consultation. Wavelet-connections were calculated for each melody in the range from 0 to 1000 ms from stimuli. Total 22 examinees in 12 patients being in unconsciousness state were carried out. Resting state values of wavelet-connectivity were poorer in vegetative patients in comparison to healthy subjects regardless of consciousness recovery degree in future while wavelet-connections in mutism were higher in comparison to healthy subjects. Absolute value of wavelet-synchrony was lower than in norm. In patients with compete consciousness recovery in the future the maximal values of wavelet-synchrony were revealed in the temporal-occipital area while in patients who in the future have been revealed in the lesser degree the maximal values of wavelet-synchrony are shown in frontal-central areas. In chronic unconsciousness patients during the listening to instrumental music the maximal wavelet-connections values were determined in the right frontal area.
