INL Oneiros device on cover of Science
The development of Oneiros system started in 2013 in DES team at INL, in collaboration with CRNL. This device is a complete miniature laboratory for the analysis of sleep in freely moving animals.
It acquires several electrocphysiology channels (EEG, ECG, EMG, EOG), external and internal temperature as well as physical activity and movements (thanks to 2 inertial measurement units).
This deveice has enabled new studies about sleep of different anaimal species in their natural environment.
P.-A. libourel and W.Y. Lee have carried out a study thanks to this system on chinstrap penguins in the Antartic.
They not only confirmed that these animals have sleep offshore, but also they are capable on coast to get short naps (few seconds) hundred of times per hour.
