Slide 8: Conclusion

Slide 18: Narcolepsy

• Channels needed: EEG (staging), EOG (eye movement), Chin EMG (tone), Nasal airflow (breathing), Thoracic/Abdominal belts (effort), O2 Sat.
• EEG pattern: Arousal (sudden alpha intrusion/spindle burst) following an apnea termination. This fragments sleep, preventing N3/REM.

Slide 15 — Developmental & Aging Changes

• EEG/sleep differences across lifespan: infants, adolescents, older adults
• Decline in slow-wave sleep and spindle density with age

Role in Sleep Studies: EEG is a core component of polysomnography, used to differentiate between wakefulness and various sleep stages. 2. Core EEG Waveforms eeg and sleep physiology ppt

EEG Patterns During Sleep Stages

• EEG Tracing: Low voltage, mixed frequency, desynchronized.
• Physiology: High sympathetic tone. Muscle artifacts are common.
