Eeg And Sleep Physiology Ppt [repack] -

Drowsy states, light sleep, and NREM Stage 1 and 2 sleep.

Electroencephalography (EEG) is a non-invasive technique used to record the electrical activity of the brain. Sleep physiology is the study of the physiological changes that occur during sleep. Understanding the relationship between EEG and sleep physiology is crucial for diagnosing and treating sleep disorders.

Absence of slow rolling eye movements; stable, moderate muscle tone. Stage N3: Deep Sleep (Slow-Wave Sleep / SWS) eeg and sleep physiology ppt

EEG is a core component of polysomnography, the gold-standard sleep study. The American Academy of Sleep Medicine (AASM) has established standardized methods for scoring sleep stages, arousals, and other events.

Sharp, high-voltage negative deflections followed by a slower positive component, lasting at least 0.5 seconds. They protect sleep by suppressing cortical arousal to non-threatening environmental noises. Non-REM Stage 3 (N3): Deep / Slow-Wave Sleep (SWS) Drowsy states, light sleep, and NREM Stage 1 and 2 sleep

Caused by a profound loss of orexin-producing neurons. Clinically, it manifests as Sleep-Onset REM Periods (SOREMPs) , where the patient bypasses NREM sleep and plunges directly into REM within 15 minutes of sleep onset. Parasomnias:
