"Webb3 feb. 2009 · Abstract. Slow waves are the most prominent electroencephalographic (EEG) feature of sleep. These waves arise from the synchronization of slow oscillations in the membrane potentials of millions of neurons. Scalp-level studies have indicated that slow waves are not instantaneous events, but rather they travel across the brain. " - Slow wave phenomenon

Webb14 feb. 2024 · Stage 3 NREM sleep also displays so-called slow oscillations, which are even slower at 0.5 to 1 Hertz. Slow oscillations may help synchronize delta waves and spindle waves, which can also occur during deep sleep. Together, delta waves and slow oscillations are referred to as slow wave activity, and this sleep stage is often called … WebbAccurate recognition and distinction of benign variants in the EEG are essential to avoid over interpretation of such findings as epileptiform, and subsequent errant diagnosis of epilepsy.
