Sleep fragmentation alters brain energy metabolism without modifying hippocampal electrophysiological response to novelty exposure

Pierre Magistretti, Jean-Marie Petit, Maxime Olivier Baud

Sleep is viewed as a fundamental restorative function of the brain, but its specific role in neural energy budget remains poorly understood. Sleep deprivation dampens brain energy metabolism and impairs cognitive functions. Intriguingly, sleep fragmentatio ...

Patient MoCap: Human Pose Estimation under Blanket Occlusion for Hospital Monitoring Applications

Alexandru Eugen Ichim, Huseyin Coskun

Motion analysis is typically used for a range of diagnostic procedures in the hospital. While automatic pose estimation from RGB-D input has entered the hospital in the domain of rehabilitation medicine and gait analysis, no such method is available for be ...

Sustained Sleep Fragmentation Induces Sleep Homeostasis in Mice

Pierre Magistretti, Jean-Marie Petit, Maxime Olivier Baud

Study Objectives: Sleep fragmentation (SF) is an integral feature of sleep apnea and other prevalent sleep disorders. Although the effect of repetitive arousals on cognitive performance is well documented, the effects of long-term SF on electroencephalogra ...

Glycogen metabolism and the homeostatic regulation of sleep

Pierre Magistretti, Igor Allaman, Jean-Marie Petit, Sophie Burlet Godinot

In 1995 Benington and Heller formulated an energy hypothesis of sleep centered on a key role of glycogen. It was postulated that a major function of sleep is to replenish glycogen stores in the brain that have been depleted during wakefulness which is asso ...

The centriolar protein CPAP G-box: an amyloid fibril in a single domain

Georgios Hatzopoulos

Centrioles are evolutionarily conserved cylindrical cell organelleswith characteristic radial symmetry. Despite their considerable size (400 nm x 200 nm, in humans), genetic studies suggest that relatively few protein components are involved in their assem ...

Sleep Apnea Detection using Features from the Respiration and the ECG recorded with Smart-Shirts

Jean-Marc Vesin, Leila Mirmohamadsadeghi, Andréa Buttu, Grégoire Millet, Sibylle Fallet

The automatic detection of sleep apnea episodes, without the need of polysomnography and outside a clinical facility, could help facilitate the diagnosis of this disorder. In this work, features to detect sleep apnea events were computed from respiration a ...
