We all know that low correlations don't mean that they are necessarily dissimilar – our measurements could be noisy. So how do you correct for this? Our slightly nerdy, but hopefully useful preprint takes a deep dive: https://www.biorxiv.org/content/10.64898/2026.03.21.713393v226 Mar 2026 17:08 +0000at://did:plc:dknsu3kpykiskpc7bwrkvwoo/app.bsky.feed.post/3mhy3r7kxoc2thttps://bsky.app/profile/diedrichsenjorn.bsky.social/post/3mhsqawx7bk2aAlso out today - A quick intro piece on the role of the cerebellum in cognition. What does it do? How will we find out? This is what @actlab.bsky.social and I think the critical questions are right now. It was fun to write - especially the section on evolution.... https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.300368824 Mar 2026 13:59 +0000at://did:plc:dknsu3kpykiskpc7bwrkvwoo/app.bsky.feed.post/3mhsqawx7bk2ahttps://bsky.app/profile/diedrichsenjorn.bsky.social/post/3mhspwdgje22aFor nearly two decades resting-state fMRI has ruled supreme. And resting-state is suprisingly powerful. But we can do so much better by using broad batteries of tasks with the right design. Here a double-punch delivered by two papers from @carobellum.bsky.social and @basselarafat.bsky.social!

In a time where some political leaders think they can threaten whole nations it seems more meaningful than ever to become part of a free, friendly and peaceful nation.16 Mar 2026 18:25 +0000at://did:plc:dknsu3kpykiskpc7bwrkvwoo/app.bsky.feed.post/3mh73gh3kts2vhttps://bsky.app/profile/diedrichsenjorn.bsky.social/post/3mgvqattuak27Now out in Journal of Neuroscience: https://www.jneurosci.org/content/early/2026/02/22/JNEUROSCI.1797-25.2026.long How are motor memories and sensory information combined when you are playing the piano? Congrats to Amin and Medha! I know having a paper out may seem small and insignificant against all that happens in the world right now!13 Mar 2026 01:11 +0000at://did:plc:dknsu3kpykiskpc7bwrkvwoo/app.bsky.feed.post/3mgvqattuak27https://bsky.app/profile/diedrichsenjorn.bsky.social/post/3mgrxvmx6ec2m@carobellum.bsky.social really wanted to know how well resting-state correlations can predict which areas co-activate over a wide array of tasks. It turns out that you are better off running a short Multi-task battery, even if the tasks are completely different from the ones you want to predict!

Over the years, I have found that this can be a very confusing and misleading concept.
