Analysis of Variability of Isopotential Areas Features in Sequences of EEG Maps

The aim of the study was to analyse differences in dynamics of variability of extreme isopotential areas in sequences of EEG maps containing seizure activity episode. Analysis of dynamics of alternating variability of extreme isopotential areas was performed in the three steps: visual examination, calculation of the differencing coefficient and statistical analysis. Results of the study performed on two groups of totally 17 subjects reveal the different dynamics of isopotential areas variability in considered groups of patients.
