Eeg And Sleep Physiology Ppt May 2026

The relationship between the electroencephalogram (EEG) and sleep physiology is fundamental to understanding how our brains transition from alert wakefulness to restorative rest. An EEG records the electrical activity of the cerebral cortex, providing a "brain wave" map of these physiological changes. I. Introduction to EEG in Sleep Science Definition : An EEG measures variations in brain electrical potential using scalp electrodes. Key Brain Waves : Beta (13–30 Hz) : Associated with alert wakefulness and concentration. Alpha (8–12 Hz) : Seen during relaxed wakefulness with eyes closed. Theta (4–7 Hz) : Predominant in light sleep (N1). Delta (0.5–4 Hz) : Large, slow waves characteristic of deep, slow-wave sleep (N3). II.
