This Sleep Spindles database was collected during the DREAMS project, to tune, train and test our automatic detection algorithms.
It consist of 8 excerpts of 30 minutes of central EEG channel (extracted from whole-night PSG recordings), annotated independently by two experts in sleep spindles.
In order to facilitate future research and performance comparision, we decided to publish these data on Internet. Be simply aware that this DREAMS Spindles Database of University of MONS - TCTS Laboratory (Stéphanie Devuyst, Thierry Dutoit) and Université Libre de Bruxelles - CHU de Charleroi Sleep Laboratory (Myriam Kerkhofs) is under terms of the Attribution-NonCommercial-NoDerivs 3.0 Unported (CC BY-NC-ND 3.0) License.

The data were acquired in a sleep laboratory of a belgium hospital using a digital 32-channel polygraph (BrainnetTM System of MEDATEC, Brussels, Belgium). They consist of height polysomnographic recordings coming from patients with different pathologies
(dysomnia, restless legs syndrome, insomnia, apnoea/hypopnoea syndrome). Two EOG channels (P8-A1, P18-A1), three EEG channels
(CZ-A1 or C3-A1, FP1-A1 and O1-A1) and one submental EMG channel were recorded. The standard European Data Format (EDF) was used for storing. The sampling frequency was 200Hz, 100Hz or 50Hz. A segment of 30 minutes of the central EEG channel was extracted from each whole-night recording for spindles scoring. No effort was made to select good spindle epochs or noise free epochs, in order to reflect reality as well as possible. These excerpts were given independently to two experts for sleep spindles scoring. The second expert only scored the 6 first excerpts. The corresponding whole night recordings were also previously scored in sleep stages according to the Rechtschaffen and Kales criteria,but no note of these stages quotations was given to the scorers.
