Slide 1: Title Slide
For decades, sleep was considered a passive state of “brain rest.” However, with the advent of Electroencephalography (EEG), we now understand sleep as an active, dynamic, and highly structured physiological process. This article serves as a detailed companion to a PowerPoint presentation designed for medical students, sleep technicians, or neuroscience enthusiasts. We will dissect how the EEG machine captures the electrical symphony of the sleeping brain, the physiological changes that accompany each stage, and why understanding this is critical for diagnosing sleep disorders.

If you want, I can: generate slide text for each slide, produce annotated EEG trace images, or produce the AASM quick-reference table next. Which would you like? Alpha (α) Waves (8–13 Hz):

| Rhythm | Frequency | State | | :--- | :--- | :--- | | Beta | 13-30 Hz | Awake, alert, anxious | | Alpha | 8-13 Hz | Awake, relaxed, eyes closed | | Theta | 4-8 Hz | Light sleep (N1), drowsiness | | Delta | 0.5-4 Hz | Deep sleep (N3), regeneration |
