The article presents an original method for the automatic assessment of the quality of event-related poten-tials(ERPs),based on the calculation of the coefficient ε,which describes the compliance of recorded ERPs with some statistically significant parameters.This method was used to analyze the neuropsychological EEG monitoring of patients suffering from migraines.The frequency of migraine attacks was correlated with the spatial distribution of the coefficientsε,calculated for EEG channels.More than 15 migraine attacks per month was accompanied by an increase in calcu-lated values in the occipital region.Patients with infrequent migraines exhibited maximum quality in the frontal areas.The automatic analysis of spatial maps of the coefficient ε demonstrated a statistically significant difference between the two analyzed groups with different means of migraine attack numbers per month.
