A self-supervised implicit neural representation framework for estimating Standard Model of white matter parameters improves accuracy under noise conditions, enables spatial upsampling, and allows integrated gradient non-uniformity correction. @maxchamb.bsky.social www.nature.com/articles/s42...

Geometry-driven deformation produces short-range U-fibers around the central sulcus; with realistic curvature and organization; again without any diffusion data.

This suggests cortical folding provides a powerful anatomical prior for white-matter organization and tractography.

How does this work?

Starting from a smooth, fetal-like cortex, we place simple radial fibers — then let cortical folding simulation do the rest.

🧠New preprint!

What if cortical geometry alone already encodes much of white-matter organization?

We introduce a subject-specific, reversible cortical folding model that unfolds and refolds the brain from a single T1w MRI; no diffusion, no ML.
