Automatic Sleep Stages Classification Using EEG Entropy Features and Unsupervised Pattern Analysis Techniques
José Luis Rodríguez-Sotelo,Alejandro Osorio-Forero,Alejandro Jiménez-Rodríguez,David Cuesta-Frau,E.M. Cirugeda-Roldan,Diego Peluffo +5 more
TL;DR: This work proposes a new automatic sleep classification method based on unsupervised feature classification algorithms recently developed, and on EEG entropy measures, which reached up to an average of 80% correctly classified stages for each patient separately while keeping the computational cost low.
Journal ArticleDOI
Thalamic reticular control of local sleep in mouse sensory cortex.
Laura M. J. Fernandez,Gil Vantomme,Alejandro Osorio-Forero,Romain Cardis,Elidie Béard,Anita Lüthi +5 more
TL;DR: The data indicate a previously unrecognized heterogeneity in a powerful forebrain oscillator that contributes to sensory-cortex-specific and dually regulated NREMS, enabling local sleep regulation according to use- and experience-dependence.
Journal ArticleDOI
Regulation of Local Sleep by the Thalamic Reticular Nucleus
TL;DR: Novel cellular and functional insights supporting TRN heterogeneity and how these elements come together to account for local NREM sleep are reviewed and open questions arising from these studies are discussed.
Journal ArticleDOI
Noradrenergic circuit control of non-REM sleep substates.
Alejandro Osorio-Forero,Romain Cardis,Gil Vantomme,Aurélie Guillaume-Gentil,Georgia Katsioudi,Christiane Devenoges,Laura M. J. Fernandez,Anita Lüthi +7 more
TL;DR: In this article, the authors demonstrate that consolidated mouse NREMS is a brain state with recurrent fluctuations of the wake-promoting neurotransmitter noradrenaline on the ∼50-s timescale in the thalamus.
Journal ArticleDOI
When the Locus Coeruleus Speaks Up in Sleep: Recent Insights, Emerging Perspectives
TL;DR: Novel dynamic assessments of noradrenaline signaling and LC activity uncover a rich diversity of activity patterns that establish the LC as an integral portion of sleep regulation and function.
