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).

🚨 I'm searching for a full-time research coordinator to join my group & work on precision brain 🧠 network and cognitive control projects at both 3T and 7T. Please rt 🙌 Applications due: Feb. 26 Start date: flexible, as early as June More 👇 #neuroskyence #PsychSciSky

For 15(!) years I’ve been teaching introductory #MRI to grad students, and struggled to find a textbook for a wide variety of backgrounds. I'm happy to share an online textbook I created, fully open source (including code for generating figures and plots shown): larsonlab.github.io/MRI-educatio...

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. scim.ag/3LkRfRY

FWIW: our group collects a lot of highly-accelerated fMRI at 3T and 7T; as you know the single band reference images have a ton more contrast than the accelerated data. However, I've never once needed to use them because afni_proc does so well with alignment and blip-up/down distortion correction.

A lot of people think that every international student admitted means one fewer spot for domestic students, when the opposite is more likely true - the tuition revenue international students bring allows public universities to provide substantial discounts to domestic students, improving access.
