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 ...
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 ...
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 ...
Validity of actigraphy for nighttime sleep monitoring in hospitalized patients with traumatic injuries
(American academy of sleep medicine, 2020-02-15)
Study objectives: Sleep-wake disturbances are frequent among patients hospitalized for traumatic injuries but remain poorly documented due to the lack of tools validated for hospitalized patients. This study aimed to ...
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 ...
A longitudinal investigation of sleep and daytime wakefulness in children and youth with concussion
(SAGE, 2019-01-10)
A high proportion of adults who sustain a concussion identify changes in their sleep during the acute stage, typically
reporting an increased need for sleep or nonrestful sleep. Our understanding of sleep following ...
The impact of poor sleep on cognition and activities of daily living after traumatic brain injury : a review
Sleep and everyday activities after TBI
(Wiley, 2014)
Background/aim : Patients frequently report sleep disrup-tions or insomnia during their hospital stay, particularlyafter a traumatic brain injury (TBI). The consequences ofthese sleep disturbances on everyday activities ...
Disentangling the direction of associations between sleep and temperament in toddlers
(Taylor & Francis, 2019-06-24)
Objectives/Background: Although much research has investigated the associations between
children’s sleep and their temperament, the direction of these associations remains unclear,
largely due to a lack of longitudinal ...
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 ...
