Rapid eye movement (REM) sleep is a unique stage characterized by a highly active brain—with EEG patterns very similar to wakefulness—coupled with skeletal muscle atonia (paralysis). This paradoxical stage is where most vivid dreaming occurs and is crucial for emotional regulation and memory processing. The "sawtooth waves" are specific sharp waves sometimes seen just before or during bursts of REM sleep.
The physiological changes during sleep are profound and affect nearly every system in the body. These changes are critical for restoring and maintaining health, and understanding them is key to diagnosing sleep disorders. : A standardized method to ensure reproducible electrode

Understanding the physiology allows for the diagnosis of sleep pathologies: Difficulty initiating or maintaining sleep.
In a typical clinical setting, an overnight PSG involves the recording of multiple biosignals:
Electroencephalography (EEG) is the gold standard for monitoring brain activity and the cornerstone of sleep medicine. Whether you are preparing a lecture, a clinical seminar, or a slide deck, understanding the intersection of EEG and sleep physiology is essential. 1. Core Principles of EEG in Sleep Medicine
