The SS5 subset of the Montreal Archive of Sleep Studies (MASS) cohort is an open-access database of laboratory-based polysomnography (PSG) recordings defined as :
- 26 subjects (age 25±7.4 years, age range: 20-59 years)
- 13 males (age 23±2.2 years, age range: 20-27 years)
- 13 females (age 26.9±10 years, age range: 20-59 years)
- 26 PSG recordings (whole night) "* PSG.edf"
- 20 electrodes in the EEG montage
- reference is linked-ear reference with a 10 kΩ resistance (LER)
- 2 EOG channels
- 3 referential EMG
- 1 ECG channel
- 26 Sleep staging files "* Base.edf"
- Sleep stage scoring rules : R&K
- Page size (s) : 20
Notes: The EMG channels are referential and not bipolar as stated in the paper (O'Reilly 2014).
Sleep stage scoring does not necessarily start at the beginning of the PSG recording.
Muscular artefact detections are available in the dataset named "SS5 Sleep Annotations" (https://doi.org/10.5683/SP3/7BBHEH).
