Dr. Tianye Zhai’s careful and exhaustive new paper evaluating the effects of numerous fMRI denoising pipeline components, alone and in combination, just came out in HBM - check it out! onlinelibrary.wiley.com/doi/10.1002/...

In-scanner thoughts contribute to resting-state functional connectivity pubmed.ncbi.nlm.nih.gov/42365014/ I've long thought that this is the "elephant in the room" of resting state #fMRI esp. for comparing groups. If two groups think & feel differently in the scanner, of course rsfMRI will differ!

You can track respiration during fMRI using the phase images of your EPI scan; the fMRI respiration tracking toolbox got an update. github.com/alexjaffray/...

I’m very sad to share that Howard Fields has died. He made seminal discoveries in pain modulation, placebo, and addiction. He was also a wonderful mentor and friend who taught me how to think about the brain and the joy of scientific discovery. www.iasp-pain.org/publications...

Selecting an effect size for power analysis is hard. Many researchers fall back on Cohen's thresholds, but they have no empirical basis and vary wildly by field. Our new paper offers a better option: field-specific effect size distributions built from meta-analytic data doi.org/10.3758/s134...

After rereading the cool hidden brain paper (www.frontiersin.org/journals/sys...) I decided to make a new version. Code and everything available here: github.com/koerding/neu... Most popular: hippocampus. Why are diagonal band, medial geniculate nucleus, and interposed nucleus so unpopular?

so i guess dcm2bids died because they made breaking changes multiple times? codebase hasn't been updated in years. what are people using now?

How do we define "good" fMRI data? Especially with resting state, there are circularity risks if we evaluate data quality as showing the networks we expect to see. Javier Gonzalez-Castillo (& me & others) developed pBOLD, a new metric that uses multi-echo info. www.biorxiv.org/content/10.6... 1/8

For 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!

Thanks so much @tknapen.bsky.social and Gilles de Hollander for their @openneuro.bsky.social upload of a special ODC dataset. Was able to replicate the ODC findings from your subject 6 using my afni_proc + SUMA-based pipeline. i'll post the LH below.

🧠 Resting-state fMRI is often treated as the gold standard for studying the brain’s intrinsic organization. But is it actually the best way to estimate functional architecture? We tested this directly. 🧵1/8

If you teach young aspiring scientists, the new "Crash Course Scientific Thinking" on youtube is quite good. Up to episode 5 right now. Honestly, should be mandatory viewing in junior highs in the US, IMO.

I've been testing Claude to see how well it can "vibe out" a stat. power app that I've already coded completely myself - so I know what I want. It mostly gets things right with animations (those are easily verifiable) but looking into the backend stats code is nightmare inducing (see pic).

Today I am excited to introduce respyra - an open-source Python toolbox for respiratory tracking experiments in interoception research! Now on PyPI (pip install respyra) with a preprint on PsyArXiv: osf.io/preprints/ps... GitHub: github.com/embodied-com...
