- 19 subjects (age 23.6±3.7 years, age range: 18-33 years)
- 8 males (age 24.3±4.2 years, age range: 19-33 years)
- 11 females (age 23.2±3.5 years, age range: 18-30 years)
The SS2 subset includes sleep events annotations marked by experts such as sleep spindles and k-complexes.
Expert 1 scored the sleep spindles and k-complexes for all the subjects.
Expert 2 scored the sleep spindle for 15 out of 19 subjects.
The subsets includes 53 annotations files "*.edf":
- Sleep spindles marked by expert 1 (19 files "* Spindles_E1.edf")
- Sleep spindles marked by expert 2 (15 files "* Spindles_E2.edf")
- K-Complexes marked by expert 1 (19 files "* KComplexes_E1.edf")
The subset includes 19 sleep stages files "* Base.edf". The sleep stages are the same as those included in the dataset named "SS2 Biosignals and Sleep stages"
Sleep stage scoring :
- Rules : R&K
- Page size (s) : 20
Notes: Expert 2 only scored sleep spindles for 15 out of 19 subjects.
The sleep stages are the same as those included in the dataset named "SS2 Biosignals and Sleep stages".
