Sleep slow waves’ negative-to-positive-phase transition : a marker of cognitive and apneic status in aging
(Oxford University Press, 2022-10-11)
The sleep slow-wave (SW) transition between negative and positive phases is thought to mirror synaptic strength and likely depends
on brain health. This transition shows signifcant age-related changes but has not been ...
Are age and sex effects on sleep slow waves only a matter of EEG amplitude ?
(Oxford University Press, 2020-09-15)
Aging is associated with reduced slow wave (SW) density (number SW/min in nonrapid-eye movement sleep) and amplitude.
It has been proposed that an age-related decrease in SW density may be due to a reduction in ...
Sleep spindles are resilient to extensive white matter deterioration
(Oxford University Press, 2020-06-13)
Sleep spindles are an essential part of non-rapid eye movement sleep, notably involved in sleep consolidation, cognition, learning
and memory. These oscillatory waves depend on an interaction loop between the thalamus and ...
EEG connectivity across sleep cycles and age
(American academy of sleep medicine, 2019-11-06)
Study Objectives
In young adults, sleep is associated with important changes in cerebral connectivity during the first cycle of non-rapid eye movement (NREM) sleep. Our study aimed to evaluate how electroencephalography ...
Brain white matter damage and its association with neuronal synchrony during sleep
(Oxford University Press, 2019-01-28)
The restorative function of sleep partly relies on its ability to deeply synchronize cerebral networks to create large slow oscillations observable with EEG. However, whether a brain can properly synchronize and produce a ...
Sleep in the acute phase of severe traumatic brain injury : a snapshot of polysomnography
Sleep and traumatic brain injury
(SAGE, 2015-12-23)
Background and Objectives. The onset of pervasive sleep-wake disturbances associated with traumatic brain injury (TBI) is poorly understood. This study aimed to (a) determine the feasibility of using polysomnography in ...
Are NREM sleep characteristics associated to subjective sleep complaints after mild traumatic brain injury?
Sleep after mild TBI
(Elsevier, 2015-04)
Sleep complaints are common after mild traumatic brain injury (mTBI). While recent find-ings suggest that sleep macro-architecture is preserved in mTBI, features of non-rapid eye movement(NREM) sleep micro-architecture ...
Actigraphy data in pediatric research : the role of sleep diaries
Actigraphy and sleep diary
(Elsevier, 2018-01)
Background. When assessing children's sleep using actigraphy, researchers usually rely on a sleep diary completed by a parent as an aid in scoring actigraphic data. However, parental nonadherence in completing the sleep ...
