Abstract : The report is concerned with the use of computer to define stages of sleep from EEG data. Results from eight laboratories indicate a general overall agreement of 80-85% between computer sleep stage scoring and human scoring. The computer was unable to separate stage REM sleep from stage 1 based upon EEG data alone. Like the human scorer, the computer scoring often confused stages 3 and 4. The relative advantages of Fourier transform analysis, period analysis, the digital computer, the special purpose computer, and a specific sleep scoring instrument were discussed. (Author)
