Our internal "body clock." Located in the Suprachiasmatic Nucleus (SCN) of the hypothalamus, it operates on a roughly 24-hour cycle. Light detection via the retina entrains the SCN to the day/night cycle, regulating the release of Melatonin from the pineal gland to induce sleepiness at night. eeg and sleep physiology ppt
0.5 seconds and are also characteristic of Stage N2. They can occur spontaneously or in response to external auditory stimuli. 4. The Architecture of Sleep: Stages and EEG Criteria – Title, Presenter Name, Institutional Affiliation
: Predominantly delta waves; critical for physical restoration. The Architecture of Sleep: Stages and EEG Criteria
High amplitude, low frequency. These represent deep, slow-wave sleep (NREM Stage 3). 4. The Stages of Sleep and Their EEG Signatures
Disrupted slow-wave sleep transitions can trigger sleepwalking or night terrors (NREM parasomnias), while a lack of muscle atonia during REM indicates REM Sleep Behavior Disorder (RBD). 5. Slide-by-Slide PPT Presentation Outline
Slow, rolling eye movements; decreased muscle tone compared to wakefulness. Stage N2: Light to Moderate Stable Sleep
