Electroencephalography (EEG) and Sleep Physiology Subtitle: Understanding Brain Waves and the Architecture of Sleep Presenter Name: [Your Name] Date: [Date]
Electroencephalography (EEG) is a non-invasive technique used to record the electrical activity of the brain. Sleep physiology is the study of the physiological changes that occur during sleep. Understanding the relationship between EEG and sleep physiology is crucial for diagnosing and treating sleep disorders. eeg and sleep physiology ppt
Marked by Sleep-Onset REM Periods (SOREMPs), where a patient bypasses NREM stages and drops directly into REM sleep within minutes of falling asleep. Presentation Design Tips for "EEG and Sleep Physiology"
High-amplitude peaks often triggered by environmental stimuli. Stage N3 (Deep Sleep): Classification of Brain Waves (Beta, Alpha, Theta, Delta)
An EEG works by attaching small metal discs called electrodes to the scalp to detect electrical impulses generated by brain cells.
EEG signals are categorized by their frequency (measured in Hertz, Hz) and amplitude (measured in microvolts, µV). Identifying these waveforms is essential for accurate sleep staging. Marked by Sleep-Onset REM Periods (SOREMPs), where a
To initiate sleep, the wake-promoting circuits must be inhibited.
Deep N3 sleep is highly concentrated in the first third of the night. Conversely, REM sleep periods grow progressively longer and more intense toward the morning hours.
Rapid eye movements on EOG and flat-line muscle activity on EMG. 5. Visualizing the Night: The Hypnogram
