Report: EEG and Sleep Physiology

1. Introduction

The electroencephalogram (EEG) is a fundamental tool in sleep medicine. It records the brain’s electrical activity non-invasively, allowing researchers and clinicians to characterize the different stages of sleep. This report outlines the physiological basis of sleep, the distinct EEG patterns associated with each stage, and the clinical relevance of these findings.

While EEG looks similar to Stage N1, it is distinguished by EOG (eye movement) and EMG (muscle tone) sensors. National Institutes of Health (.gov) 4. Clinical Applications Glymphatic clearance:

EEG and Sleep Physiology: A Comprehensive Overview Electroencephalography (EEG) is the primary tool used to study the neurophysiological changes that occur during sleep. By recording electrical activity from the scalp, EEG allows researchers and clinicians to categorize sleep into distinct stages and identify physiological markers of health and disorder. 1. Fundamentals of Sleep EEG

  • Ventrolateral preoptic nucleus (GABA & galanin) inhibits wake centers.
  • Glymphatic clearance:
    1. NREM (Non-Rapid Eye Movement) Sleep – 75–80% of total sleep.
    2. REM (Rapid Eye Movement) Sleep – 20–25% of total sleep.
