- Reposted by Bart LarsenEver wondered how white matter tracts actually map onto the cortical hierarchy and cognition—beyond the usual “projection vs association” labels? Our new preprint tackles exactly that! 🧠✨ doi.org/10.64898/202... Thread below 🧵
- Very happy to share our paper on the "summer slide" in kid's cognitive test scores is out now in @pnas.org! We find a replicable dip in performance across multiple domains of cognition in >23,000 kids across 4 datasets! Check out the 🧵 from @ariellekeller.bsky.social below! 👇
- Our paper on the ☀️ "summer slide" 🛝 is out now @pnas.org! www.pnas.org/doi/10.1073/... Summer slide is a replicable phenomenon across diverse datasets that's more than "forgetting" school material in vacation months, but effects of socioeconomic inequality are ➡️ 7x bigger! ⬅️ #PsychSciSky #DevPsy 🧵👇

We discuss how experience - particularly adversity - interacts with neuroplasticity during human development authors.elsevier.com/c/1mB5U4sIRv...

- Reposted by Bart LarsenIs the “standard workflow” holding back fMRI analysis? Mass-univariate analysis is still the bread-and-butter: intuitive, fast… and chronically overfitted. Add harsh multiple-comparison penalties, and we patch the workflow with statistical band-aids. No wonder the stringency debates never die.
- I can't recommend this fantastic new review from @valeriejsydnor.bsky.social enough! It does an amazing job of synthesizing the current state of the literature and then looking forward to provide a fresh perspective on how to move this work forward in humans. Check it out!
- Happy to share our review "Investigating hierarchical critical periods in human neurodevelopment” in @npp-journal.bsky.social! We examine neurobiological, environmental & behavioral evidence for human critical periods in sensory and association cortex +discuss new research directions rdcu.be/eMkVU 🧵

- Reposted by Bart LarsenI am beyond excited to announce that ggplot2 4.0.0 has just landed on CRAN. It's not every day we have a new major #ggplot2 release but it is a fitting 18 year birthday present for the package. Get an overview of the release in this blog post and be on the lookout for more in-depth posts #rstats

- 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!
- How does the human brain coordinate hierarchical cortical development? Our work in Nature Neuroscience identifies a role for thalamocortical structural connectivity in the expression of hierarchical periods of cortical plasticity & environmental receptivity in youth 🧵 www.nature.com/articles/s41...
- Reposted by Bart LarsenOK, 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.
- Alert! ... for the child development world! @fluxsociety.bsky.social @fitngin.bsky.social The Healthy Brain and Child Development (HBCD) Study has released its first data wave - it’s massive. Check here: docs.hbcdstudy.org and here: nbdc-datahub.org Here’s why it matters 🧠🍼
- Reposted by Bart LarsenExcited 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" 🧠 #neuroskyence #neuroimaging #psychscisky
- ✨New Preprint!✨ Sex differences in psychiatric disorders often show up in adolescence as disparities in prevalence, symptoms, and treatment outcomes. We aimed to understand sex diffs in brain organization that might lead to these disparities! t.ly/x6oxC 🧵⬇️ #neuroskyence #psychscisky #Neuroimaging
- Reposted by Bart LarsenWhile 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!
- Excited to share the first major piece of work and preprint from my lab! Led by Jason Kim! 🥳🎉🤘 www.biorxiv.org/content/10.1...

- Reposted by Bart LarsenTonight 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).
- Reposted by Bart LarsenWe 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... 1/n

- Reposted by Bart LarsenFor 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

- Reposted by Bart Larsenhey -- 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!
- Reposted by Bart LarsenThank 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!
- 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! www.nature.com/articles/s41...

- 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...
