Subjects wore a miniature telemetry system with very good signal quality described in. The PSGs of about 9 hours were recorded in the hospital during two nights, one of which was after temazepam intake, and the other of which was after placebo intake. Subjects had mild difficulty falling asleep but were otherwise healthy. The 44 ST* files (ST = Sleep Telemetry) were obtained in a 1994 study of temazepam effects on sleep in 22 Caucasian males and females without other medication. Subjects and recordings are further described in the file headers, the descriptive spreadsheet SC-subjects.xls, and in. Oro-nasal airflow, rectal body temperature and the event marker were also sampled at 1Hz. The submental-EMG signal was electronically highpass filtered, rectified and low-pass filtered after which the resulting EMG envelope expressed in uV rms (root-mean-square) was sampled at 1Hz. The EOG and EEG signals were each sampled at 100 Hz. The first nights of subjects 36 and 52, and the second night of subject 13, were lost due to a failing cassette or laserdisk. įiles are named in the form SC4 ssNEO-PSG.edf where ss is the subject number, and N is the night. Subjects continued their normal activities but wore a modified Walkman-like cassette-tape recorder described in chapter VI.4 (page 92) of Bob’s 1987 thesis. Two PSGs of about 20 hours each were recorded during two subsequent day-night periods at the subjects homes. The 153 SC* files (SC = Sleep Cassette) were obtained in a 1987-1991 study of age effects on sleep in healthy Caucasians aged 25-101, without any sleep-related medication.

Corresponding hypnograms (sleep patterns) were manually scored by well-trained technicians according to the Rechtschaffen and Kales manual, and are also available. Some records also contain respiration and body temperature. The sleep-edf database contains 197 whole-night PolySomnoGraphic sleep recordings, containing EEG, EOG, chin EMG, and event markers.
