[Periods and amplitude distribution parameters of the EEG in mental stress--on the concordance of mechanical and visuomanual methods of evaluation].
Mean frequency, % index and mean amplitudes in 3 frequency bands served as basis for a dynamic comparison of manual and computer assisted EEG analyses in healthy adults. In spite of inevitable methodical deviations it was possible to assume quite a good concordance for the significant data trends with but one exception. Among others the mean frequencies proved to be predicative variables in the EEG functional test with eyes opened. The satisfactory result provides arguments for a greater involvement of automated methods for quantitative description of the EEG activity in clinical practice.
