This paper truly exemplifies what is possible in the modern era of neuroimaging data. A beautiful and extremely impressive piece of work from @valeriejsydnor.bsky.social that was a treat to contribute to. Check it out!

OK, It is not just the HBCD release...
docs.hbcdstudy.org

It’s the ABCD Release time too!
docs.abcdstudy.org
nbdc-datahub.org

That means the ABCC 3.0.0 is live!!!

The largest release yet from the ABCD-BIDS Community Collection.

This is going to be fun!!
👇 Let’s dig in.

Excited to share that our paper is now in press at the British Journal of Psychiatry! Looking forward to presenting our work this Friday at #SOBP2025 in our symposium: "Does one size fit all? Subgroup Modeling of Brain-Behavior Relationships in Psychiatry" 🧠

While the world burns, we cook up a new preprint! doi.org/10.1101/2025...

Biophysical modeling is a key tool to derive mechanistic insights into the brain. These models are governed by biologically meaningful parameters (unlike artificial neural networks), but the dirty secret ... 1/N

Awesome opening salvo from the lab of @lindenmp.bsky.social!! Super cool work that will stem many future directions!

Age-related differences in 1/f aperiodic EEG/MEG signals can be driven by cardiac rather than brain activity 👇

AOC and Bernie in front of the rally crowd in Denver

Zoomed out crowd shot of 34,000 people in downtown Denver with Colorado mountains in the background

Tonight an unbelievable **34,000 people** gathered for our Denver rally to take on billionaires and win our country back.

This was the largest political gathering in Denver since Obama in 2008.

Also bigger than the 2024 DNC.

And the largest ever rally in Bernie’s career (and obviously, mine too).

We think of white matter as the brain's highways—uniform conduits between cortices. But what if we study development along tracts? Turns out the journey matters as much as the cortical destination! We're thrilled to share “Two Axes of White Matter Development” www.biorxiv.org/content/10.1...

Indirect Costs at NIH . . . I wasn’t planning on spending part of a Saturday writing about cost accounting principles and the like, but NIH-world was hit with a doozy of a policy announcement on Friday night:

Great analysis of the indirect cost rate announcement by @stuartbuck.bsky.social

For those who don't know, here are very real research costs that directs cannot cover - all fall within indirects: the buildings we work in (upkeep, maintenance, cleaning, etc), utilities, IT infrastructure, human resources, administrative staff, security, and lots more

Finally out in its polished form 🤩 New methodological avenues that help facilitate looking at individual brain functional organization in developmental populations 👶🧠

Psychedelic mental health research is booming—but how do we keep up with rapidly evolving evidence? 🌱 Our team proposes a living evidence synthesis approach to ensure clinicians, policymakers, and the public have access to the latest, most reliable data.

hey -- i'm hiring a postdoc! the ad will be up shortly, but looking for someone with network neuroscience experience (very broadly). the position isn't tied to any specific project/grant, so lots of flexibility in terms of what you'd actually *do*. hmu if you might be interested/want to learn more!

Thank you, Dr. Fair! It was really a rewarding experience for me to collaborate with your team from #MIDB! @drdamienfair.bsky.social @tervoclemmensb.bsky.social @bart-larsen.bsky.social Thank you for all your efforts and expertise you put into this work; they truly made this work better!

Study design features increase replicability in brain-wide association studies - Nature Optimizing study design is critical for increasing standardized effect sizes and replicability, and the features that increase replicability in cross-sectional and longitudinal brain-wide association ...

Congratulations @kaidikang.bsky.social et al on their paper in Nature.

Also proud of the team at #MIDB in the support! @tervoclemmensb.bsky.social @bart-larsen.bsky.social and more!

If you are interested in optimizing study designs, take a look, it's a great read!

We're excited to release new versions of our BIDS-Apps for processing and analyzing #dmri data, QSIPrep and QSIRecon! Our team has been working hard to prepare these pipelines to process infant data and bring them in line with the @nipreps.bsky.social ecosystem. #neuroimaging #nipreps #bids 1/10

👏👏👏 @ariellekeller.bsky.social et al. with cyclical GAMs, multi-dataset replication, and study planning relevance!

Very happy with how this one turned out!
This started as a curiosity, that built into a side project, and eventually into a very cool paper!
This was also super fun to work on with @ariellekeller.bsky.social! Check out her thread below and the preprint here: osf.io/preprints/ps...

Super excited to share our official ACORN Lab website!! 🍁🧠

Prevalence of Iron Deficiency and Iron-Deficiency Anemia in US Females Aged 12-21 Years, 2003-2020 This study examines prevalence of iron deficiency among females aged 12 to 21 years to inform future screening strategies for iron deficiency and iron-deficiency anemia.

Just your regular reminder that ~40% of menstruating adolescents (and likely an even higher proportion of adults) suffer from iron deficiency and yet we don’t universally screen.
