  • Are age and sex effects on sleep slow waves only a matter of EEG amplitude ? 

    Rosinvil, Thaïna; Bouvier, Justin; Dubé, Jonathan; Lafrenière, Alexandre; Bouchard, Maude; Cyr-Cronier, Jessica; Nadia, Gosselin; Carrier, Julie; Lina, Jean-Marc (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 electroencephalogram (EEG) amplitude ...

  • EEG connectivity across sleep cycles and age 

    Bouchard, Maude; Lina, Jean-Marc; Gaudreault, Pierre-Olivier; Dubé, Jonathan; Gosselin, Nadia; Carrier, Julie (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 (EEG) connectivity during sleep ...

  • Sleep slow waves’ negative-to-positive-phase transition : a marker of cognitive and apneic status in aging 

    Lafrenière, Alexandre; Lina, Jean-Marc; Hernandez, Jimmy; Bouchard, Maude; Gosselin, Nadia; Carrier, Julie (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 investigated in pathological ...
