Microstructure Informed Tractography: Pitfalls and Open Challenges.

Frontiers in neuroscience

Daducci A, Dal Palú A, Descoteaux M, Thiran JP.
PMID: 27375412
Front Neurosci. 2016 Jun 06;10:247. doi: 10.3389/fnins.2016.00247. eCollection 2016.

One of the major limitations of diffusion MRI tractography is that the fiber tracts recovered by existing algorithms are not truly quantitative. Local techniques for estimating more quantitative features of the tissue microstructure exist, but their combination with tractography...

Nonparametric Bayes Models of Fiber Curves Connecting Brain Regions.

Journal of the American Statistical Association

Zhang Z, Descoteaux M, Dunson DB.
PMID: 32265576
J Am Stat Assoc. 2019;114(528):1505-1517. doi: 10.1080/01621459.2019.1574582. Epub 2019 Apr 30.

In studying structural inter-connections in the human brain, it is common to first estimate fiber bundles connecting different regions relying on diffusion MRI. These fiber bundles act as highways for neural activity. Current statistical methods reduce the rich information...

Surface-Based Connectivity Integration: An atlas-free approach to jointly study functional and structural connectivity.

Human brain mapping

Cole M, Murray K, St-Onge E, Risk B, Zhong J, Schifitto G, Descoteaux M, Zhang Z.
PMID: 33956380
Hum Brain Mapp. 2021 Aug 01;42(11):3481-3499. doi: 10.1002/hbm.25447. Epub 2021 May 06.

There has been increasing interest in jointly studying structural connectivity (SC) and functional connectivity (FC) derived from diffusion and functional MRI. Previous connectome integration studies almost exclusively required predefined atlases. However, there are many potential atlases to choose from...

BACKGROUND: The visualization and analysis of brain data such as white matter diffusion tractography and magnetic resonance imaging (MRI) volumes is commonly used by neuro-specialist and researchers to help the understanding of brain structure, functionality and connectivity. As mobile...

Real-time multi-peak tractography for instantaneous connectivity display.

Frontiers in neuroinformatics

Chamberland M, Whittingstall K, Fortin D, Mathieu D, Descoteaux M.
