Sleep in Functional Motor Disorders: A Case–Control Polysomnographic Study

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep problems are frequent in functional motor disorders (FMDs). Surprisingly, objective correlates of impaired sleep and its relationship to other comorbidities have been understudied, and no polysomnographic study is available. We aimed to map the polysomnographic parameters in the context of self‐reported sleep and mood symptoms and search

Sleep and Rhythmic Profile After Pineal Gland Removal in Humans

Journal of Sleep Research, EarlyView.
ABSTRACT Melatonin, a hormone produced by the pineal gland, is classically described as a central circadian modulator. However, the impact of its absence on circadian rhythmicity in humans remains poorly understood. Pinealectomised patients, in whom melatonin secretion is chronically suppressed, represent a valuable clinical model to investigate the ...

Cerebral and Peripheral Hemodynamics Across Wakefulness and NREM Sleep

Journal of Sleep Research, EarlyView.
ABSTRACT Wake/sleep‐related changes in cerebral hemodynamic oscillations are well established, but similar changes in peripheral hemodynamics remain largely understudied. Moreover, how the relationship between cerebral and peripheral hemodynamics varies across sleep–wake states is not well understood, despite evidence that these oscillations in the low‐

Sleep Slow Wave‐Bistability and the Connection Between the Sleeping Brain and the Environment—Neurobiological Considerations

Journal of Sleep Research, EarlyView.
Bistability is an inherent working mode of NREM sleep. Those bistable patterns ‐ sleep slow waves, K‐complexes, and the cyclic alternating pattern (on a longer, several seconds' time‐scale) ‐ have a double function; they protect sleep and provide an interface between the brain and the environment for information‐transfer during sleep.
