This study examines distortions in electrooculogram (EOG) wave form of slow eye movements (SEM) during the wake‐sleep transition. Distortions in AC‐coupled EOG, which were evaluated by computing Pearson's product‐moment correlation coefficient between DC‐ and AC‐coupled EOG, decreased as a function of time constants (0.3, 3 and 6 s) and showed SEM‐dependent changes. Time constants of longer than 3.0 s should be chosen to reliably recognize SEM.
