Diffusion MRI (dMRI) is a powerful tool to study white matter maturation. In our new preprint, we process and distribute a new resource of >24,000 ABCD dMRI scans using open source tools! We then evaluate how methods shape inferences about development.

Thanks to the amazing work by @uwescience.bsky.social's Noah Benson, NeuroHackademy now has a beautiful new website, with an emphasis on improved accessibility: neurohackademy.org
Super interesting! Are there are already any findings on aphantasia, or is this project just starting?
๐๏ธ Announcing IST 2026 in the Canadian Rockies!
The 2nd annual meeting of the International Society for Tractography is happening this fall. Following Bordeaux, weโre gathering researchers, clinicians & developers pushing tractography, diffusion MRI & brain connectivity forward.

I am thrilled to announce that our group has received a new grant from the Shurl and Kay Curci Foundation to study the neural dynamics of vocal learning in children! I am looking for a postdoc to join us in this effort, currently funded for 2 years. Please reach out with CV and letter of interest.
A first for me: a paper I didn't write was published in a supposedly peer-reviewed journal I've never heard of with me as the sole named author. It's a bibliometric analysis of a field that I have done some work in, so there's a plausible connection, but that's not me.
We think of white matter as the highways of the brain. But when we followed development along those highways, we were surprised. The journey is more complex than we thought. My final PhD paper, โTwo Axes of White Matter Developmentโ, is now out in @natcomms.nature.com! ๐ฃ๏ธ๐ง โจ

Applications for NeuroHackademy 2026 are now open! This is a two-week NIH-funded summer experience that combines neuroimaging and data science in a summer school / experiential hackathon: neurohackademy.org/apply/
@uwpsychology.bsky.social @uwescience.bsky.social
My first preprint is out! Thank you to my brilliant collaborators & mentors for making this possible @vmarchman.bsky.social @arokem.org @jyeatman.bsky.social, as well as everyone behind the awesome open source software that we use @pennlinc.bsky.social @cieslakmatt.bsky.social (& many not on bsky)
๐จ I'm searching for a full-time research coordinator to join my group & work on precision brain ๐ง network and cognitive control projects at both 3T and 7T. Please rt ๐
Applications due: Feb. 26
Start date: flexible, as early as June

Where was this published? I believe it's an editorial at a Nature/Springer journal based on the font/layout, but which one? Do you have a link to the original?
This is a fantastic interview in which a 300-page book is summarized into 15 minutes of (very fast!) talking. What I really came here to ask though is whether "asshole to appetite" is an existing idiom, or did CD make that up?
The brown m&m of scientific communication
One of my graduate school mentors said that they would never review an article in more than one journal, because the authors deserve to hear someone else's opinion

@joann-trejo.bsky.social, @marymunson4.bsky.social and I have a commentary in @natcellbio.nature.com on recent attacks on DEI in biomedical research: "If scientific research, especially biomedical research, is meant to serve everyone, then it requires that everyone has an opportunity to participate"
Join us for the #NeuroHackademy Neuroimaging and Data Science networking event at this year's @sfn.org meeting. Tues. Nov. 18th from 7โ9pm at the Marriott Marquis, Grand Ballroom 4. The event is free; food and drink will be available for purchase from the hotel.

Excited to share that our work introducing the Reproducible Brain Charts (RBC) data resource is now published in Neuron!! ๐

Very cool! Also works when written as 9/16/2025, but no longer has the elegance of 3^2/4^2/5^2

Y'all set a very high bar in terms of the empathy you bring to your interactions with stakeholders (in the sense of being able to consider their viewpoint). The balance with "foundational contributions" really sets you apart in this ecosystem (and I'd hope gives you a "competitive edge"!)
We've been experimenting and improving our practices in building healthy relationships with open source communities, here's our latest thinking on how we approach this important topic!
Yes, but there are details. Maybe best discussed on an issue or on neurostars?
Yeah, the intonation is somehow a bit weird and the graphics are ... what they are. But it also looks like it mostly got the gist of it, and many correct details, so altogether not bad. Thanks for sharing!
Ha! I am curious, but:
Excited to share that my TEDx talk is finally available online. I loved sharing what the science shows us: that it's time to reframe adolescence - from problem to โจ potential โจ 1/
