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. Webb27 aug. 2024 · Abstract. Sleep slow waves are studied for their role in brain plasticity, homeostatic regulation, and their changes during aging.
