The problem of defining EEG alpha activity, and of detecting and measuring it, is outlined. Some advantages of a threshold method are presented and compared with an amplitude-integration method. Characteristics of percent-time scoring, based upon observable alpha spindles in the waking EEG, are discussed. A probability distribution of percent-time alpha as a function of detection threshold is derived and compared with empirical data.
本文概述了定义脑电图α波活动以及检测和测量它的问题。介绍了阈值法的一些优点，并与振幅积分法进行了比较。讨论了基于清醒脑电图中可观察到的α波纺锤波的百分比时间评分的特征。推导了作为检测阈值函数的百分比时间α波的概率分布，并与经验数据进行了比较。
