Electroencephalography, Electromyography, and Electro-oculography: General Principles and Basic Technology

摘要: A detailed understanding of the principles electroencephalography (EEG) is one cornerstones in interpretation polysomnography (PSG). The ability to analyze EEG channels for staging sleep, as well identification abnormal signals clinical relevance, plays a central role generating meaningful PSG report. Sleep medicine intricately intertwined with EEG. In fact, seeds sleep may have been sown when Aseninsky and Kleitman first discovered rapid eye movement (REM) 1953 (Aserinsky Science 118:273–274, [1]). With explosion research into other physiological changes increased recognition need measure biological functions such respiratory parameters, limb movements, gastric pH, penile tumescence among others, became subsumed just many parameters described during polygraphic study. Nevertheless, basic competence an essential component skill set any polysomnographer.
