Eeg And Sleep Physiology Ppt [cracked]
This presentation content on EEG and Sleep Physiology is structured to cover the fundamental science of brain activity, the stages of human sleep, and the clinical application of EEG monitoring. Slide 1: Introduction to EEG and Sleep Definition Electroencephalography (EEG)
- Most difficult to arouse.
- Growth hormone secretion peaks.
- Essential for physical restoration, immune function, and declarative memory consolidation.
Slide 14: Thermoregulation
Questions?
- Stage 1 NREM Sleep: EEG shows a mix of alpha and theta waves.
- Stage 2 NREM Sleep: EEG shows a distinctive pattern of slow oscillations (spindles) and K-complexes.
- Stage 3 and 4 NREM Sleep: EEG shows high-amplitude delta waves.
- REM Sleep: EEG shows a rapid, low-voltage pattern similar to wakefulness.
Slide 20 — Case Studies (2 brief cases)
- Case A: Obstructive sleep apnea — fragmented sleep, reduced SWS, EEG arousals (show-mini traces)
- Case B: Narcolepsy type 1 — SOREMPs (sleep-onset REM periods) on MSLT/PSG
- Drifting in and out of sleep.
- Easily awakened.
- Muscle tone decreases.
- Sensation of falling (hypnic jerk) may occur.
