Cerebellum responds to language like cortical areas
One of four language-responsive cerebellar regions may encode meaningful information, much like the cortical language network in the left hemisphere, according to a new study.

The first Canadian paper from @sivanjo.bsky.social: when we started this work, I thought the cerebellar articulation areas would just look like the speech area in M1. Not so. Check it out! @coltoncasto.bsky.social
New preprint is live! 🎉
We (@diedrichsenjorn.bsky.social , @basselarafat.bsky.social, and I) studied how the brain represents syllables during speech, and which cortical representations the cerebellum most closely resemble.
Feedback very welcome:

This is an amazing success story. We are happy to have published several papers there - it really has become the top neuroimaging journal within just two years. Kudos to all who had the courage to make it happen!
Launched in 2023, Imaging Neuroscience is now firmly established, with full indexing (PubMed, etc.) and 700 papers to date.
We're very happy to announce that we are able to reduce the APC to $1400.
Huge thanks to all authors, reviewers, editorial team+board, and MIT Press.

Variance partitioning is used to quantify the overlap of two models. Over the years, I have found that this can be a very confusing and misleading concept. So we finally we decided to write a short blog to explain why.

Exited to share tomorrow new updates on trying to figure out how the neocortex and cerebellum talk to each other. Work by @carobellum.bsky.social, Ali Shabazi, and others in the lab!
To understand cortico-cerebellar connectivity in humans, the usual approach is to exploit the correlations of functional brain imaging signals during rest.
In this talk, Jorn Diedrichsen will present results suggesting that a better approach is to measure co-activation during specific tasks.
