[Wavelet analysis and its application in investigation of brain potentials during verbal task solving]

The components of event-related brain potentials during verbal tasks were investigated with the help of a new method--wavelet analysis. Using this method in 415 ms from the beginning of the stimulus maximum values of the higher frequent components were revealed in the left parietal zone. During a repetition of verbal task a tendency for a decrease of amplitude values of the higher frequent components was observed.
