A tractogram can hold millions of streamlines. QuickBundles groups them by shape into representative tracts, QuickBundlesX does it ~22–25× faster!

Speedy, spiraling electrical waves may be key to brain’s information flow

Rotating neuronal waves are built into brain anatomy and help coordinate far-flung regions, mouse imaging study suggests

[allen institute @AllenInstitute]

Traveling waves in the brain don't just move — they spiral, and it's brain-wide. New research from @UW, with @AllenInstitute contributions, out today in @ScienceMagazine, shows the brain's own wiring shapes the pattern.

We kicked off our 2026 #NeuroEngineering Research in Development Series (#NERDS) this past week! This student-driven series showcases graduate and postdoctoral students from across our twenty-three core members and keeps us all up-to-date on our research portfolio.

What matters most for childhood brain organization?

We analyzed 649 variables.
The answer: Socioeconomics (SES); with brain patterns pointing at sleep & stress as drivers.

Even brain-IQ associations were better explained by SES confounding.

Can lesion network mapping predict survival in children with brain tumors? Collaboration with UCL and @Brain_Circuits in @Nature suggests the answer is yes. Cutting the tumor off from this network may confer survival benefit.

Corriveau-Lecavalier et al. show that patterns of default mode network dysfunction predict future conversion to amyloid positivity, mild cognitive impairment, and dementia, emphasizing the role of network dyshomeostasis in Alzheimer’s disease. https://t.co/B14bNHaYdf

NEW RELEASE:

Today we're releasing CortexMAE: a family of fMRI foundation models trained on 2.1K hours of open fMRI data.

We're also releasing Brainmarks: an open benchmark suite for evaluating fMRI foundation models.

Full paper is on arXiv (accepted to ICML 2026)
