Sustained sleep fragmentation affects brain temperature, food intake and glucose tolerance in mice

Pierre Magistretti, Jean-Marie Petit, Maxime Olivier Baud

Sleep fragmentation is present in numerous sleep pathologies and constitutes a major feature of patients with obstructive sleep apnea. A prevalence of metabolic syndrome, diabetes and obesity has been shown to be associated to obstructive sleep apnea. Whil ...

The psychostimulant modafinil enhances gap junctional communication in cortical astrocytes

Pierre Magistretti, Jean-Marie Petit, Joël Gyger, Xinhe Liu

Sleep wake cycle is characterized by changes in neuronal network activity. However, for the last decade there is increasing evidence that neuroglial interaction may play a role in the modulation of sleep homeostasis and that astrocytes have a critical impa ...

Challenging the sleep homeostat: Sleep in depression is not premature aging

Mirjam Münch

Objectives: The close relationship between major depression and sleep disturbances led to the hypothesis of a deficiency in homeostatic sleep pressure in depression (S-deficiency hypothesis). Many observed changes of sleep characteristics in depression are ...

The Impact of Sleep Fragmentation on Sleep Homeostasis, Brain and Peripheral Energy Metabolism and Spatial Learning

Maxime Olivier Baud

The quality of sleep has recently come to the forefront of public health concerns in industrialized nations. Indeed, voluntary sleep curtailment is widespread, sleep disorders are increasingly recognized and both correlate with the current epidemiology of ...

Age effects on spectral electroencephalogram activity prior to dream recall

Mirjam Münch

Ageing is associated with marked changes in sleep timing, structure and electroencephalographic (EEG) activity. Older people exhibit less slow-wave and spindle activity during non-rapid eye movement (NREM) sleep, together with attenuated levels of rapid ey ...

Energy-Aware Traffic Engineering

Dejan Kostic, Nedeljko Vasic

Energy consumption of the Internet is already substantial and it is likely to increase as operators deploy faster equipment to handle popular bandwidth-intensive services, such as streaming and video-on-demand. Existing work on energy saving considers loca ...

Metabolic response of the cerebral cortex following gentle sleep deprivation and modafinil administration

Pierre Magistretti, Jean-Marie Petit, Christophe Kopp

Objectives: The main energy reserve of the brain is glycogen, which is almost exclusively localized in astrocytes. We previously reported that cerebral expression of certain genes related to glycogen metabolism changed following instrumental sleep deprivat ...

Evaluation of energy homeostasis

Johan Auwerx

Body mass and composition reflect the combined effects of three processes: energy intake, energy partitioning (storage), and energy expenditure. Energy is released from food as it is combusted to carbon dioxide and water, and is expended as heat and work w ...
