An electroencephalogram (EEG) is a non-invasive, safe, and painless diagnostic test that records electrical activity generated by brain neurons. It is the cornerstone of , which is the gold standard for diagnosing sleep disorders.
: Low-voltage, mixed-frequency background waves. You will often see unique "sawtooth waves" —triangular, jagged 2–6 Hz runs that precede bursts of eye movements.

The "sleep debt" that builds up the longer we stay awake. It is reflected in the intensity of delta waves during N3. Process C (Circadian Rhythm): eeg and sleep physiology ppt

Alpha waves are most prominent in the occipital region when the eyes are closed and relaxed. They are immediately blocked (or "desynchronized") by eye-opening or mental concentration—a phenomenon known as the Alpha Block .
An EEG measures brain activity through the scalp, providing crucial data that allows researchers and clinicians to differentiate between wakefulness, non-rapid eye movement (NREM) sleep, and rapid eye movement (REM) sleep. This article covers the essential concepts of EEG and sleep physiology often featured in scientific presentations (PPTs). 1. Introduction to EEG in Sleep Medicine An electroencephalogram (EEG) is a non-invasive, safe, and
If you want, I can:
PSG is the gold standard for evaluating sleep disorders. It is a multi-parametric test that records .
To accurately identify REM sleep on a slide, look for three co-occurring signals: You will often see unique "sawtooth waves" —triangular,
In a clinical setting, we rarely look at EEG alone. Sleep is diagnosed using , a multi-parametric study that typically includes:
Sleep is not a static state of unconsciousness but an active, highly regulated physiological process. Macrostructure: The Sleep Cycle
