On the cortical connectivity in the macaque brain: A comparison of diffusion tractography and histological tracing data

NeuroImage, 2020
Diffusion-weighted magnetic resonance imaging (DW-MRI) tractography is a non-invasive tool to probe neural connections and the structure of the white matter.

Evaluating structural connectivity disruption after stroke: individual tractography or the use of a model-based approach?

NeuroImage: Clinical
Background: Ischemic stroke disrupts structural connectivity between grey matter regions, influencing functional outcomes. Diffusion MRI-based tractography allows assessment of white matter damage and may guide rehabilitation.

Addressing the path-length-dependency confound in white matter tract segmentation.

PLoS ONE, 2014
We derive the Iterative Confidence Enhancement of Tractography (ICE-T) framework to address the problem of path-length dependency (PLD), the streamline dispersivity confound inherent to probabilistic tractography methods.

The challenge of mapping the human connectome based on diffusion tractography

Nature Communications, 2017
Though tractography is widely used, it has not been systematically validated. Here, authors report results from 20 groups showing that many tractography algorithms produce both valid and invalid bundles.
