Mapping of the electroencephalogram (EEG) has been found to be a valuable method in clinical neuropsychopharmacology. It is evident that careful treatment of artifacts is of utmost importance for EEG data processing, as artifacts that contaminate the EEG data can lead to spurious results. The artifactprocessing method described in this article splits signal analysis into a preprocessing step, yielding individual electro-oculographic (EOG) regression factors for EOG minimization and into a processing step, yielding target variables. The combination of avoiding, minimizing and identifying artifacts, as well as visual checking of face validity, will help remove artifactual effects from the EEG. © 1992.
