A new MRI protocol can scan the human brain and its venous network in under 7 minutes at 0.35 mm iso. resolution, marking it as a potential tool for diagnosing cerebrovascular diseases and monitoring neurodegeneration.

We show that we can derive measures like cortical thickness aligned to the biological ground-truth —bringing cerebellar imaging closer to the level of detail already available in the cerebrum.
We observe a convergent interlobular gradient in cortical thickness and vascular-density. This heterogeneity seems driven by the granular layer cytoarchitecture when comparing to 3D histology. Still work to be done though to further improve SNR and segmentation fidelity.
Until recently, getting a reliable in-vivo approximation of the human cerebellar cortex was out of reach.
New high resolution fMRI paper describing the capabilities and challenges of 9.4T fMRI in the cerebellum.

How do we make sense of very brief events?
@gianfrancof.bsky.social, @valeriacentanino.bsky.social & @dbueti.bsky.social show, in a unifying framework, the multiple stages and mechanisms the brain uses to build time perception.

and yet one more: routine cerebellar neuroimaging at 9.4T—no individual B1+ calibration, robust BOLD. A glimpse of what’s to come at even higher fields. in MRM onlinelibrary.wiley.com/doi/10.1002/... with Wietske van der Zwaag, @highonfield.bsky.social, Desmond Tse 🎓🧠 #fMRI #cerebellum #9.4T
It's the second paper in the same day with mesoscale/UHF/vascular imaging in the title (check out also the new paper of @ofgulban.bsky.social and Dimo Ivanov in Science Advances www.science.org/doi/10.1126/...). A sign of things to come
🎓🧠 It's finally out in @pnas.org 📄

We reconstruct the cerebellar cortex and vasculature in-vivo by combining motion-corrected, pTX-enabled #7T MRI with a new segmentation approach.

Duration perception involves multiple brain regions, but how unimodal tuning across this network supports subjective timing remains unclear. This study shows that parietal, premotor, and caudal SMA en...
