Presentation Title: The Electroencephalogram and the Architecture of Sleep
Paradoxically, the EEG during REM resembles wakefulness, showing "sawtooth" waves and low-voltage, mixed-frequency activity. While the brain is highly active (dreaming), the body experiences muscle atonia to prevent the physical enactment of dreams. Clinical and Research Significance Monitoring these waveforms through Polysomnography (PSG)
Sleep is divided into two main stages: non-rapid eye movement (NREM) sleep and rapid eye movement (REM) sleep. eeg and sleep physiology ppt
Definition:
Sleep is a naturally recurring state of mind and body, characterized by altered consciousness, inhibited sensory activity, and inhibition of nearly all voluntary muscles. the EEG during REM resembles wakefulness
