[Automatic analysis of sleep EEG].
Since a manual of standardized scoring system for sleep stage was reported by APSS, the sleep researches remarkable advanced. But it took sleep researchers many times and effort to analysis of numerous data. The digital and computer technique were advanced about 10 years, so that, paper polysomnography(PSG) has been replaced with computerized polysomnography(PSG). The computerized PSG is useful for sleep stage scoring and storage of data. It is pointed out that the correctness of computerized analysis unfortunately is less than visual. Generally, computerized analysis is performed to apply the manual of APSS. This manual is not able to computerized analysis. Because this manual was developed for visual. In 1999, Japanese sleep research society was reported a manual of sleep stage scoring for computerized analysis which was modified the manual of APSS. It is expected to development of computerized PSG system which is able to yield the result similar to that obtained with visual.
