Sleep stages are conventionally scored according to recommendations by a committee chaired by Rechtschaffen and Kales in 1968. With these rules normal sleep is divided into rapid eye movement sleep and non-rapid eye movement sleep. Non-rapid eye movement sleep is subdivided into four further stages. With the Rechtschaffen and Kales scoring system the dominant sleep stage at any one time is scored. However, the dynamic structure of sleep is not adequately shown. Furthermore, there is considerable interscorer variability, the scoring is time consuming, tedious and difficult to perform. To overcome these limitations automatic sleep scoring devices using processed EEG technology are developed. These developments are discussed in this chapter.
睡眠阶段通常根据1968年由 Rechtschaffen 和 Kales 主持的委员会的建议进行评分。按照这些规则，正常睡眠分为快速眼动睡眠和非快速眼动睡眠。非快速眼动睡眠又进一步细分为四个阶段。使用Rechtschaffen 和 Kales评分系统，对任一时刻的主要睡眠阶段进行评分。然而，睡眠的动态结构没有得到充分体现。此外，评分者之间存在相当大的差异，评分耗时、繁琐且难以执行。为了克服这些局限性，人们开发了使用经处理的脑电图技术的自动睡眠评分设备。本章将讨论这些进展。
