title: [Estimation of the validity of variational characteristics of pre- and poststimulus EEG by the chi-square test].
abstract: Theoretical analysis of variational characteristics was performed and their practical validity was proved as applied to electroencephalogram. These characteristics are remarkable for both simplicity of computer calculation and the fact that they reflect the most essential features of an EEG curve with a highest possible compression.
