The aim of the study was analysis of histograms of selected sequences of EEG maps to assess variability of isopotential areas. In clinical practice this variability is evaluated using visual inspection that is subjective and may be difficult in revealing of subtle differences. Variability of isopotential areas is manifested by changes of isopotential areas as well as changes of their topolocalisation. The histograms of total map areas include the information concerning the ispotential area variability, while histogram analysis of particular areas of map may be useful for evaluation of variability of isopotential areas configuration. Basing on the examples containing the period before, during and after generalized seizure activity, the variability of constellations of isopotential areas in EEG maps and related to that diversity of their histogram types were presented. The work includes examples of series of EEG map histograms with their statistical analysis and the description of method used for the quantitative assessment of the histogram series variability for the maps sequences containing seizure activity.
