Sleep is regulated by the complex interplay of two distinct internal forces, conceptualized by Alexander Borbély as the . 1. Process C: The Circadian Rhythm
Orexin (hypocretin) neurons in the lateral hypothalamus stabilize this switch. A deficiency in orexin destabilizes the boundaries between wake and sleep, causing the sleep disorder known as Narcolepsy. To effectively present the physiology, a comparison table
To initiate sleep, the wake-promoting circuits must be inhibited.
Direct transition from wakefulness to REM sleep. AI responses may include mistakes
Sharp, biphasic waveforms lasting at least 0.5 seconds. They consist of a sudden negative sharp deflection followed by a slower positive component. K-complexes can occur spontaneously or in response to auditory stimuli. EOG: No eye movements. EMG: Moderately decreased muscle tone. 4. Stage N3 (Slow-Wave Sleep / Deep Sleep)
Highly diminished muscle tone; no eye movements. Rapid Eye Movement (REM) Sleep
