Assessing feasibility and reproducibility of a bundle-specific framework on in vivo axon diameter estimates at 300mT/m

Jean-Philippe Thiran, Alessandro Daducci, Gabriel Girard, David Paul Roger Romascano, Maxime Descoteaux, Muhamed Barakovic, Jonathan Rafael Patino Lopez, Giorgio Innocenti

In vivo quantitative estimation of axon diameter in the white matter could bring new tools to study the structural and functional architecture of the brain. Recently, the feasibility of axon diameter estimation with diffusion-weighted MRI (DW-MRI) has been ...

Resting-State Networks of Adolescents Experiencing Depersonalization-Like Illusions: Cross-sectional and Longitudinal Findings

Dimitri Nestor Alice Van De Ville, François Lazeyras

The mirror-gazing task (MGT) experimentally induces illusions, ranging from simple color changes in the specular image of oneself, to depersonalization-like anomalous self-experiences (ASE) as in experiencing one's specular image as someone else. The objec ...

Intra- and extra-axonal axial diffusivities in the white matter: Which one is faster?

Nicolas Kunz, Ileana Ozana Jelescu, Analina Raquel Hausin

A two-compartment model of diffusion in white matter, which accounts for intra- and extra-axonal spaces, is associated with two plausible mathematical scenarios: either the intra-axonal axial diffusivity Da,‖ is higher than the extra-axonal De,‖ (Branch 1) ...

In-vivo Bundle-Specific Axon Diameter Distributions Estimation across the Corpus Callosum

Jean-Philippe Thiran, Alessandro Daducci, Gabriel Girard, David Paul Roger Romascano, Muhamed Barakovic, Maxime Descoteaux

Over the last decade microstructure imaging has become commonly endorsed to estimate quantitative features of neuronal tissue. However, those techniques estimate the microstructure only locally. Microstructure informed tractography was recently proposed to ...

Increasing upper limb training intensity in chronic stroke using embodied virtual reality: a pilot study

Olaf Blanke, José del Rocio Millán Ruiz, Andrea Serino, Gangadhar Garipelli, Thomas Schmidlin, Odile Hélène Chevalley

Background: Technology-mediated neurorehabilitation is suggested to enhance training intensity and therefore functional gains. Here, we used a novel virtual reality (VR) system for task-specific upper extremity training after stroke. The system offers inte ...

Quantitative Analysis of Myelin and Axonal Remodeling in the Uninjured Motor Network After Stroke

Jean-Philippe Thiran, Reto Meuli, Alessandro Daducci, Cristina Granziera, Gunnar Krüger, Djalel Eddine Meskaldji, Gloria Menegaz

Objectives: Contralesional brain connectivity plasticity was previously reported after stroke. This study aims at disentangling the biological mechanisms underlying connectivity plasticity in the uninjured motor network after an ischemic lesion. In particu ...
