The 37th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBS) took place in Milano, Italy, in the period August 25th-29th, 2015. At the meeting, Diego Sona's group presented a paper entitled "Sleep-Stage Scoring in Mice: The Influence of Data Pre-Processing on a System's Performance".

Sleep-stage analysis in mice and rats has received growing attention in recent years, due to the fact that mice display electrical activity during sleep which has underlying similarities with that of human sleep. Both conventional manual and automatic sleep-wakefulness scoring are rule based tasks which use brain waves measured by Electroencephalogram (EEG) and activity detected by Electromyography (EMG) of skeletal muscles. Several works have been conducted trying to provide an automatic sleep-scoring system on the basis of machine learning methods. In this study the authors try to understand the reasons behind the complexity of this problem and emphasize the importance of normalization procedure that leads to a better stage discrimination comparing different classification methods.
