Introduction

This REMs database was collected during the DREAMS project, to tune, train and test our automatic detection algorithms.

It consist of 9 excerpts of 30 minutes of PSG recordings in which rapid eye movements (REMs) were annotated by an experts.

In order to facilitate future research and performance comparision, we decided to publish these data on Internet. Be simply aware that this DREAMS REMs 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.

Database description

Data collected 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 9 excerpts of PSG recordings, coming from 5 healthy subjects. 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. These excerpts of 30 minutes were extracted from whole-night recordings. No care was provided to select epochs free of artifacts, but a special effort was provided to cover all sleep stages. (Indeed, sleep stages were previously scored according to the Rechtschaffen and Kales criteria, but no note of this stages cotation was provided to the scorer during the annotation in REMs).
