Fig. 4. Comparison of average (for the group) quantitative characteristics of the Brodmann area signal recorded in the situation of solving the inverse EEG problem when performing tests during the study based on the model of six EEG microstate classes (p < 0.001; Pearson's chi-squared test). a — eyes closed, b — eyes open; c — performing recognition test
