Abstract
In the present work, we show the application of new technique for spatio-temporal analysis of EEG data. The developed technique is based on the modification of the classical approach to the analysis of EEG data with the division of the whole wave activity into frequency ranges with using of continuous wavelet transform. This technique was used to assess the activity of the subject's brain in the process of increasing fatigue during prolonged exposure to monotonous cognitive load in test subjects evening after working day. Applying the developed mathematical tool to the experimental data, we demonstrate the emergence of various scenarios of the fatigue in test subjects.
