Differential language network functional connectivity alterations in Alzheimer's disease and the semantic variant of primary progressive aphasia
Montembeault, Maxime; Chapleau, Marianne; Jarret, Julien; Boukadi, Mariem; Laforce, Robert Jr.; Wilson, Maximiliano A.; Rouleau, Isabelle; Brambati, Simona Maria (Elsevier, 2019-04-03)Patients with Alzheimer's disease (AD) and semantic variant primary progressive aphasia (svPPA) can present with similar language impairments, mainly in naming. It has been hypothesized that these deficits are associated with different brain mechanisms ... -
Functional network and structural connections involved in picture naming
Jarret, Julien; Ferré, Perrine; Chedid, Georges; Bedetti, Christophe; Boré, Arnaud; Joanette, Yves; Rouleau, Isabelle; Brambati, Simona Maria (Elsevier, 2022-06-13)We mapped the left hemisphere cortical regions and fiber bundles involved in picture naming in adults by integrating task-based fMRI with dMRI tractography. We showed that a ventral pathway that “maps image and sound to meaning” involves the middle ... -
Intégration de l'imagerie par résonance magnétique fonctionnelle (IRMf) à la tractographie pour cartographier les réseaux corticaux impliqués dans la dénomination d'images
Jarret, Julien (2023-02-22)Il est de plus en plus communément admis que la plupart des fonctions cognitives chez l’humain sont organisées sous forme de réseaux cérébraux distribués plutôt que strictement sous forme de modules anatomiques ségrégués et localisés. Parmi ces fonctions ... -
Task-induced functional connectivity of picture naming in healthy aging : the impacts of age and task complexity
Ferré, Perrine; Jarret, Julien; Brambati, Simona Maria; Bellec, Pierre; Joanette, Yves (MIT Press, 2020-06-01)The topological organization of the brain, governed by the capacity of brain regions to synchronize their activity, allows for cost-effective performance during everyday cognitive activity. Functional connectivity is an fMRI method deemed task-specific ...
