Abstract

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 frequency components were revealed in the left parietal zone. During repetition of a verbal task, a tendency to a decrease in amplitude values of the higher frequency components was observed.
