Test-retest reliability of diffusion measures extracted along white matter language fiber bundles using HARDI-based tractography
(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 ...
Visual and auditory perceptual strength norms for 3,596 French nouns and their relationship with other psycholinguistic variables
(Springer, 2019-04-23)
Perceptual experience plays a critical role in the conceptual representation of words. Higher levels of semantic variables such as imageability, concreteness, and sensory experience are generally associated with faster and ...
The role of the hippocampus in the semantic variant of primary progressive aphasia : a resting‐state fcMRI study
(Wiley, 2019-09-09)
The goal of the study was to determine whether the semantic variant of primary progressive aphasia (svPPA) affects the intrinsic connectivity network anchored to left and right anterior hippocampus, but spares the posterior ...
Norms of concept familiarity and emotional valence for 3,596 French nouns and their contribution in lexical decision
(Springer, 2018-08-20)
In the last decade, research has shown that word processing is influenced by the lexical and semantic features of words. However, norms for a crucial semantic variable-that is, conceptual familiarity-have not been available ...
Deformation-based shape analysis of the hippocampus in the semantic variant of primary progressive aphasia and Alzheimer’s disease
(Elsevier, 2020-06-03)
Background
Increasing evidence shows that the semantic variant of primary progressive aphasia (svPPA) is characterized by hippocampal atrophy. However, less is known about disease-related morphological hippocampal changes. ...
Connected speech markers of amyloid burden in primary progressive aphasia
(Elsevier, 2021-10-07)
INTRODUCTION
Positron emission tomography (PET) amyloid imaging has become an important part of the diagnostic workup for patients with primary progressive aphasia (PPA) and uncertain underlying pathology. Here, we employ ...
Functional network and structural connections involved in picture naming
(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 ...
The challenge of mapping the human connectome based on diffusion tractography
(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 ...
Treatment-induced neuroplasticity after anomia therapy in post-stroke aphasia : a systematic review of neuroimaging studies
(Elsevier, 2023-08-24)
We systematically reviewed the literature on neural changes following anomia treatment post-stroke. We conducted electronic searches of CINAHL, Cochrane Trials, Embase, Ovid MEDLINE, MEDLINE-in-Process and PsycINFO databases; ...
