Sleep is not simply the absence of wakefulness. It is defined as a reversible, neurobehavioral state characterized by reduced awareness, altered metabolism, and distinct patterns of brain activity. Sleep is an active physiological process that is highly conserved across species, meaning it is fundamental to survival. On average, humans spend approximately 23 years of their lives asleep, but the quality and architecture of this sleep are far more critical than duration alone.

By understanding EEG and sleep physiology, we can better diagnose and treat sleep disorders, ultimately improving the quality of life for individuals with sleep-related problems. This article provides a comprehensive overview of the topic, and the accompanying PPT slides offer a visual representation of the concepts discussed. On average, humans spend approximately 23 years of
When awake, EEG readings show "activated" brain activity, dominated by low-voltage, fast-activity waves in the beta ( Hz) and gamma ( >30is greater than 30 Hz) range. B. NREM Sleep (Non-Rapid Eye Movement)
In conclusion, EEG and sleep physiology are closely related fields that have significantly advanced our understanding of sleep and its disorders. EEG provides a non-invasive means of recording brain activity during sleep, allowing researchers and clinicians to study sleep stages, cycles, and disorders. This comprehensive guide in PPT format provides an overview of EEG and sleep physiology, highlighting the importance of EEG in understanding sleep and its clinical applications.
