The effects of time constant on electrooculographic recording of slow eye movements during the wake-sleep transition.
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.
