  • Aging reduces the stimulating effect of blue light on cognitive brain functions 

    Daneault, Véronique; Hébert, Marc; Albouy, Geneviève; Doyon, Julien; Dumont, Marie; Carrier, Julie; Vandewalle, Gilles (Oxford University Press, 2014-01-01)
    Study Objectives: Light exposure, particularly blue light, is being recognized as a potent mean to stimulate alertness and cognition in young individuals. Aging is associated with changes in alertness regulation and cognition. Whether the effect of ...

  • 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 ...

  • Regional cerebral blood flow during wakeful rest in older subjects with mild to severe obstructive sleep apnea 

    Cerebral perfusion in OSA
    Baril, Andrée-Ann; Gagnon, Katia; Arbour, Caroline; Soucy, Jean-Paul; Montplaisir, Jacques-Yves; Gagnon, Jean-François; Gosselin, Nadia (Oxford University Press, 2015)
    Objectives: To evaluate changes in regional cerebral blood flow (rCBF) during wakeful rest in older subjects with mild to severe obstructive sleep apnea (OSA) and healthy controls, and to identify markers of OSA severity that predict altered ...

  • Sleep-wake disturbances in hospitalized patients with traumatic brain injury: association with brain trauma but not with an abnormal melatonin circadian rhythm 

    Duclos, Catherine; Dumont, Marie; Paquet, Jean; Blais, Hélène; Van der Maren, Solenne; Menon, David K.; Bernard, Francis; Gosselin, Nadia (Oxford University Press, 2019-09-28)
    Study Objectives: To test whether the sleep-wake cycle disruption in patients hospitalized with traumatic brain injury (TBI) 1) is also found in patients with traumatic injuries other than TBI (nonTBI); and 2) is associated to a weaker or abnormal ...
