  • Brain white matter damage and its association with neuronal synchrony during sleep 

    Sanchez, Erlan; El-Khatib, Héjar; Arbour, Caroline; Bedetti, Christophe; Blais, Hélène; Marcotte, Karine; Baril, Andrée-Ann; Descoteaux, Maxime; Gilbert, Danielle; Carrier, Julie; Gosselin, Nadia (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 restorative sleep when it ...

  • 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 ...

  • The challenge of mapping the human connectome based on diffusion tractography 

    Maier-Hein, Klaus H.; Boré, Arnaud; Pinsard, Basile; Bedetti, Christophe; Desrosiers, Mathieu; Brambati, Simona Maria; Doyon, Julien; Descoteaux, Maxime (Nature research, 2017-11-07)
    Tractography based on non-invasive diffusion imaging is central to the study of human brain connectivity. To date, the approach has not been systematically validated in ground truth studies. Based on a simulated human brain data set with ground truth ...

  • Sleep spindles are resilient to extensive white matter deterioration 

    Sanchez, Erlan; Arbour, Caroline; El-Khatib, Héjar; Marcotte, Karine; Blais, Hélène; Baril, Andrée-Ann; Bedetti, Christophe; Descoteaux, Maxime; Lina, Jean-Marc; Gilbert, Danielle; Carrier, Julie; Gosselin, Nadia (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 the cortex, which relies on ...

  • Test-retest reliability of diffusion measures extracted along white matter language fiber bundles using HARDI-based tractography 

    Boukadi, Mariem; Marcotte, Karine; Bedetti, Christophe; Houde, Jean-Christophe; Desautels, Alex; Deslauriers-Gauthier, Samuel; Chapleau, Marianne; Boré, Arnaud; Descoteaux, Maxime; Brambati, Simona Maria (Frontiers media, 2019-01-14)
    High angular resolution diffusion imaging (HARDI)-based tractography has been increasingly used in longitudinal studies on white matter macro- and micro-structural changes in the language network during language acquisition and in language impairments. ...
