 Hypnogram graphically illustrating typical sleep architecture with the slow wave sleep of non‐REM stages III and IV predominantly located in the first half of the night and REM sleep cycles (shaded boxes) featuring more prominently during the latter half of sleep.

 Characteristic 30 s epoch polysomnographic traces of REM and non‐REM sleep stages II and IV in a 4 year old child. Note EEG (black), EOG (blue) and EMG (red). (A) Stage II sleep: low voltage mixed frequency EEG and characteristic K complexes (large positive deflection followed by negative deflection for >0.5 s) and 12–14 Hz spindles. (B) Stage IV sleep: EEG high amplitude slow wave (⩽4 Hz) for >50% of the epoch. EOG reflects the high frequency activity of EEG. (C) REM sleep: low voltage mixed frequency EEG with characteristic saw‐tooth waves. There was conjugate eye movement on EOG in this epoch and marked suppression of tone on sub‐mental EMG.
