  • Aging and language : maintenance of morphological representations in older adults 

    Royle, Phaedra; Steinhauer, Karsten; Dessureault, Émie; Herbay, Alexandre C.; Brambati, Simona Maria (Frontiers media, 2019-05-15)
    Studies employing primed lexical decision tasks have revealed morphological facilitation effects in children and young adults. It is unknown if this effect is preserved or diminished in older adults. In fact, only few studies have investigated ...
  • 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 ...
  • Cerebral white matter diffusion properties and free‐water with obstructive sleep apnea severity in older adults 

    Baril, Andrée‐Ann; Gagnon, Katia; Descoteaux, Maxime; Bedetti, Christophe; Chami, Sirin; Sanchez, Erlan; Montplaisir, Jacques-Yves; De Beaumont, Louis; Gilbert, Danielle; Poirier, Judes; Pelleieux, Sandra; Osorio, Ricardo S.; Carrier, Julie; Gosselin, Nadia (Wiley, 2020-03-13)
    Characterizing the effects of obstructive sleep apnea (OSA) on the aging brain could be key in our understanding of neurodegeneration in this population. Our objective was to assess white matter properties in newly diagnosed and untreated adults with ...
  • 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 ...
  • Gray matter hypertrophy and thickening with obstructive sleep apnea in middle-aged and older adults 

    Gray matter increases with obstructive sleep apnea
    Baril, Andrée-Ann; Gagnon, Katia; Brayet, Pauline; Montplaisir, Jacques-Yves; De Beaumont, Louis; Carrier, Julie; Lafond, Chantal; L’Heureux, Francis; Gagnon, Jean-François; Gosselin, Nadia (American Thoracic Society, 2017-06-01)
    Rationale: Obstructive sleep apnea causes intermittent hypoxemia, hemodynamic fluctuations, and sleep fragmentation, all of which could damage cerebral gray matter that can be indirectly assessed with neuroimaging. Objectives: To investigate whether ...
  • 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 ...
  • Relationships between years of education, regional grey matter volumes, and working memoryrelated brain activity in healthy older adults 

    Boller, Benjamin; Mellah, Samira; Ducharme-Laliberté, Gabriel; Belleville, Sylvie (Springer, 2017-04)
    The aim of this study was to examine the relationships between educational attainment, regional grey matter volume, and functional working memory-related brain activation in older adults. The final sample included 32 healthy older adults with 8 to ...
