Daytime sleep has no effect on the time course of motor sequence and visuomotor adaptation learning

Friedhelm Christoph Hummel, Winifried Backhaus

Sleep has previously been claimed to be essential for the continued learning processes of declarative information as well as procedural learning. This study was conducted to examine the importance of sleep, especially the effects of midday naps, on motor s ...

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 ...

Motor Performance Is not Enhanced by Daytime Naps in Older Adults

Friedhelm Christoph Hummel, Winifried Backhaus

The impact of sleep on motor learning in the aging brain was investigated using an experimental diurnal nap setup. As the brain ages several components of learning as well as motor performance change. In addition, aging is also related to sleep architectur ...

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 ...

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 ...

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 ...

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 ...

Simulation-based evaluation of non-visual responses to daylight: proof-of-concept study of healthcare re-design

Marilyne Andersen, María Lovísa Ámundadóttir, Steven W. Lockley

The discovery of a novel non-rod, non-cone photoreceptor in the human eye that mediates a number of effects on the brain has sparked a growing interest in incorporating these non-visual effects of light into the design process of buildings. Appropriately–t ...

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 ...

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 ...
