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.

Stage N3, also known as Delta sleep or Slow-Wave Sleep (SWS), is the most restorative period. It constitutes 15–25% of total sleep time and is highly concentrated in the first third of the night.

EEG and sleep physiology represent the cornerstone of modern somnology. This guide provides a structured breakdown of the essential concepts, data, and visual components required for a professional "EEG and Sleep Physiology" presentation. 1. Introduction to Polysomnography (PSG)

: Brief, sharp, diphasic potentials lasting less than 0.5 seconds, maximum over the central scalp regions near the end of Stage N1.
According to AASM guidelines, an epoch is scored as N3 when contains slow waves that meet two conditions: Frequency : Slower than 2 Hz.
