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 ...

Effects of total sleep deprivation on the perception of action capabilities

Jean-Baptiste Mignardot

Changes in a subject's state have been shown to modulate the perceptual update of his or her action capabilities. In parallel, sleep deprivation impairs in cognitive functions. It involves common neural structures that support the perception of successfull ...

Sleep sharpens sensory stimulus coding in human visual cortex after fear conditioning

Dimitri Nestor Alice Van De Ville

Efficient perceptual identification of emotionally-relevant stimuli requires optimized neural coding. Because sleep contributes to neural plasticity mechanisms, we asked whether the perceptual representation of emotionally-relevant stimuli within sensory c ...

Modeling Resting-State Functional Networks When the Cortex Falls Asleep: Local and Global Changes

Patric Hagmann

The transition from wakefulness to sleep represents the most conspicuous change in behavior and the level of consciousness occurring in the healthy brain. It is accompanied by similarly conspicuous changes in neural dynamics, traditionally exemplified by t ...

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 ...

Integrating non-visual effects of light into lighting simulation: challenges ahead

Marilyne Andersen, María Lovísa Ámundadóttir, Steven W. Lockley

Lighting is a major influential factor that affects human health and sense of wellbeing in the built environment. Since 2002, when the first reports on the discovery of a novel type of photoreceptor were published, a new field of study started to emerge at ...

Principal component structuring of the Non-REM sleep EEG spectrum in older adults yields age-related changes in the sleep and wake drives

Mirjam Münch

Age-related disturbances of the sleep-wake cycle can reflect ontogenetic changes in regulatory mechanisms underlying normal and pathological aging, but the exact nature of these changes remains unclear. The present report is the first attempt to apply prin ...

Evidence that the Lunar Cycle Influences Human Sleep

Endogenous rhythms of circalunar periodicity (similar to 29.5 days) and their underlying molecular and genetic basis have been demonstrated in a number of marine species [1, 2]. In contrast, there is a great deal of folklore but no consistent association o ...

Genes Involved in the Astrocyte-Neuron Lactate Shuttle (ANLS) Are Specifically Regulated in Cortical Astrocytes Following Sleep Deprivation in Mice

Pierre Magistretti, Jean-Luc Martin, Jean-Marie Petit, Joël Gyger, Sophie Burlet Godinot

Study Objectives: There is growing evidence indicating that in order to meet the neuronal energy demands, astrocytes provide lactate as an energy substrate for neurons through a mechanism called "astrocyte-neuron lactate shuttle" (ANLS). Since neuronal act ...

Altered cortical and subcortical local coherence in obstructive sleep apnea: a functional magnetic resonance imaging study

Dimitri Nestor Alice Van De Ville, Jonas Richiardi

Obstructive sleep apnea (OSA) syndrome is the most common sleep-related breathing disorder, characterized by excessive snoring and repetitive apneas and arousals, which leads to fragmented sleep and, most importantly, to intermittent nocturnal hypoxaemia d ...
