Produced in the lateral hypothalamus, this peptide stabilizes the wake state. A loss of orexin neurons results in narcolepsy. The Sleep-Promoting System

Alpha attenuation (the alpha rhythm drops to less than 50% of the epoch). It is replaced by Low-Amplitude, Mixed-Frequency (LAMF) activity, primarily in the theta range (4–7 Hz). Vertex sharp waves appear near the end of N1.

Content: Low-voltage mixed EEG, rapid eye movements, and profound submental muscle atonia. eeg and sleep physiology ppt

Muscle atonia (flat line), reflecting temporary somatic muscle paralysis to prevent acting out dreams. 4. Architectural Patterns and Clinical Pathology Normal Sleep Architecture

When reviewing these materials, it's helpful to visualize the relationship between brain activity (frequency) and sleep depth (amplitude). – Overview of ARAS vs. VLPO

This comprehensive guide breaks down the core concepts of EEG and sleep physiology. It is structured specifically to help you build a high-impact, professional PowerPoint (PPT) presentation. Slide 1: Introduction to EEG in Sleep Medicine

seconds), which fragment sleep and eradicate deep N3 and REM stages. Mixed-Frequency (LAMF) activity

– Overview of ARAS vs. VLPO, the role of GABA and Orexin.

Alpha rhythm is replaced by Low-Amplitude, Mixed-Frequency (LAMF) activity, primarily in the theta range (4–7 Hz), occupying of the epoch. Look for Vertex Sharp Waves ( EOG: Slow, rolling eye movements.

The keeps the cortex alert. It relies on neurotransmitters like acetylcholine, norepinephrine, serotonin, histamine, and dopamine. Orexin (hypocretin) neurons in the lateral hypothalamus act as a master switch to stabilize this awake state. The Sleep Promoting System
