What extensive monitoring is central to Polysomnography (PSG) measurements?

Answer

Brain waves (EEG), eye movements (EOG), and muscle activity (EMG).

Polysomnography (PSG) functions as the laboratory gold standard because it employs a comprehensive array of sensors to capture multiple physiological signals simultaneously. Specifically, Electroencephalography (EEG) is essential for recording the electrical activity of the brain, which defines sleep stages. Electrooculography (EOG) monitors eye movements crucial for identifying REM sleep periods. Furthermore, Electromyography (EMG) tracks muscle activity, which diminishes significantly during certain sleep stages. This combination provides unparalleled detail into the overall sleep architecture, which consumer devices attempt to approximate using simpler inputs.
