Journal ArticleDOI
Asynchrony of the early maturation of white matter bundles in healthy infants: Quantitative landmarks revealed noninvasively by diffusion tensor imaging
Jessica Dubois,Ghislaine Dehaene-Lambertz,Muriel Perrin,Jean-François Mangin,Y. Cointepas,Edouard Duchesnay,Denis Le Bihan,Lucie Hertz-Pannier +7 more
TL;DR: A specific maturation model, based on the respective roles of different maturational processes on the diffusion phenomena, was designed to highlight asynchronous maturation across bundles by evaluating the time‐course of mean diffusivity and anisotropy changes over the considered developmental period.
Journal ArticleDOI
Assessment of the early organization and maturation of infants' cerebral white matter fiber bundles: a feasibility study using quantitative diffusion tensor imaging and tractography.
TL;DR: A new method of quantification based on reconstructed tracts, split between specific regions, which should be more sensitive to specific changes in a bundle than the conventional approach, based on regions-of-interest is proposed.
Journal ArticleDOI
A framework to study the cortical folding patterns.
Jean-François Mangin,Denis Rivière,Arnaud Cachia,Edouard Duchesnay,Y. Cointepas,Dimitri Papadopoulos-Orfanos,Paola Scifo,Taku Ochiai,Francis Brunelle,Jean Régis +9 more
TL;DR: A framework of using artificial neuroanatomists that are trained to identify sulci from a database is developed, which relies on a renormalization of the brain warping problem, which consists in matching the cortices at the scale of the folds.
Journal ArticleDOI
Age‐related morphology trends of cortical sulci
Peter Kochunov,Jean-François Mangin,Thomas R. Coyle,Jack L. Lancaster,Paul M. Thompson,Dennis Rivière,Y. Cointepas,Jean Régis,Anita E. Schlosser,Donald R. Royall,Karl Zilles,John C. Mazziotta,Arthur W. Toga,Peter T. Fox +13 more
TL;DR: Sulcal age-related trends were found to be highly influenced by gender in the superior temporal, collateral, and cingulate sulci (P < 0.05), with males showing more pronounced age‐related change in sulcal width than females.
Journal ArticleDOI
In vivo evidence for the selective subcortical degeneration in Huntington's disease.
Gwenaëlle Douaud,Timothy E.J. Behrens,Cyril Poupon,Y. Cointepas,Saâd Jbabdi,Véronique Gaura,Narly Golestani,Pierre Krystkowiak,Christophe Verny,Philippe Damier,Anne-Catherine Bachoud-Lévi,Philippe Hantraye,Philippe Remy +12 more
TL;DR: Beyond Huntington's disease, DTI is proved here that diffusion imaging technique, associated to adequate methodological analyses, can provide insight into any neurodegenerative disorder for which some neuronal populations or connections are selectively targeted over others.
