parcelview is a small Python package that plays ROI time series on the cortex. You give it a parcellation and one or more (timeXparcel) arrays and it outputs a HTML file that runs in any browser, offline or inside a notebook, so you can email it or archive it. Code: github.com/bhvieira/par...

Over the past two years, I4R partnered with Psychological Science (@psychscience.bsky.social) on a large reproducibility project. 67 independent teams reproduced 64 articles published in 2024–2025, about 44% of eligible papers. Paper: www.econstor.eu/bitstream/10... Here's what we learned 🧵

Drawing ROIs on cortical surfaces just got a lot easier! 😍 SurfAnnotate is a free, browser-based tool I have been co-developing with Claude Code (@dlinhardt.bsky.social, @sbollmann.bsky.social, and @sampendu.bsky.social ), leveraging the @neurodesk.org infrastructure!

For the visual learners🙂 I recently refactored and restyled my website to a new framework (with the help of coding agents) and I took the time to revisit the ML visualizer, now with a write up, better formatting, and more features. Give it a try at bhvieira.github.io/mlvisualizer/

OHBM Hackathon 2026 | June 11–13 | Bordeaux Come spend three days coding and learning! The OHBM Hackathon takes place right before the OHBM Meeting at Campus Victoire, University of Bordeaux, and it's a great chance to work on projects, pick up new skills, and meet researchers.

New preprint: We’ve mapped the first whole-cortex record of human mesoscopic vessel density. The mesoscopic intracortical angioarchitecture is a heterogeneous landscape with area-specific links to traditional cortical boundaries, not a uniform backdrop. PDF: doi.org/10.64898/202...

The charts have been updated. Kaátaìra - 'Caminhos de Água' debuts at #1 in the top albums of 2026. rateyourmusic.com/charts/top/a...

Announcing Talkie: a new, open-weight historical LLM! We trained and finetuned a 13B model on a newly-curated dataset of only pre-1930 data. Try it below! with @alecrad.bsky.social and @nicklevin01.bsky.social

Happy to share our latest paper, the work of @clarajiang.bsky.social who trained brain-based predictors of depression on the UK Biobank (N=7,500 curated cases and matched controls) using AI/deeplearning as well as efficient statistical learning (BLUP). See thread below for a summary of findings

Future @ohbmofficial.bsky.social meeting dates just annouced: * 2027 - Toronto, Canada * 2028 - Yokohama, Japan www.ohbm-com.com/blog/futurem...

🎉 Announcing TabICLv2: State-of-the art Table Foundation Model, fast and open source A breakthrough for tabular ML: better prediction and faster runtime than alternatives, work by Jingang Qu, David Holzmüller @dholzmueller.bsky.social , Marine Le Morvan, and myself 👇

📢📄 Excited to share our new open-access paper in Neuroscience & Biobehavioral Reviews: a pre-registered scoping review on neuroimaging evidence for lexico-semantic processing in multilinguals 🧵 @nocelab.bsky.social www.sciencedirect.com/science/arti...

The OHBM OSSIG has been operating since 2016, hosting and promoting open science education for the OHBM community and beyond. SIGs must be renewed every 5 years. Please sign the following petition by Mon, Jan 26 to help us continue operating. Thank you! docs.google.com/document/d/1...

So the DIANA paper was retracted www.science.org/doi/10.1126/...

Heavily recommended, some of the most rewarding experiences I ever had at the OHBM were at the BrainHack and the Open Science Room. Apply even if unsure, you'll have the opportunity to have a chat with OSSIG members and get to ask questions, or send me a DM if in doubt! 🙂

How long is the world going to allow this horror to go on?

🇪🇺🤝 🇰🇷 Today, the Republic of Korea joins Horizon Europe. It is the first Asian country to take part. Korean entities can now join and lead research consortia with some of the world’s best research organisations to tackle global challenges together. More info ↓ europa.eu/!QFHCnC

For me, this work is a classic @ohbmofficial.bsky.social story: In 2023 I wasn't working with @bttyeo.bsky.social but I overheard him at his poster pointing to some accuracy curves saying "I don't why they have this particular shape". That kicked off the collab that led to these results.

Excited to share our latest preprint: "Neurosynth Compose: A Web-Based Platform for Flexible and Reproducible Neuroimaging Meta-Analysis" Here, we cover the why, what, and how of the next generation Neurosynth ecosystem for reproducible neuroimaging meta-analysis. osf.io/preprints/os...

Staying on Twitter because you like the engagement for sports or something is like hanging out in an actual Nazi bar because you like the pinball machine. Deactivate yesterday.

Proposal: A reboot of Blade Runner set in today’s world where Deckard is an ICE agent struggling with the possibility that he may unknowingly be an undocumented immigrant himself.

The neurons that encode sequential information into working memory do not fire in that same order during recall, a finding that is at odds with a long-standing theory. Read more in this month’s Null and Noteworthy. By @ldattaro.bsky.social #neuroskyence www.thetransmitter.org/null-and-not...

ℹ️ What’s next for neuroinformatics publishing? 📢 Don’t miss this Emergent Session with editors from Aperture Neuro, Imaging Neuroscience, and GigaByte 🗓️ Today: 11:30 am - 12:30 pm | 📍 Open Science Room @janinebijsterbosch.bsky.social @mallarchak.bsky.social @fmri-today.bsky.social

This is happening on Saturday, with Lucina and James!

First time on this side @ohbmofficial.bsky.social 🙂

The Open Science Room has been an exciting space at the OHBM Meeting for many years, but its future is threatened. Please sign this petition to signal your support for preserving a dedicated space for the OSR at future meetings. ohbm.github.io/osr2025/peti...

Privileged view from my poster, #157 "Decomposing the evaluation of probabilistic prediction of future cognitive decline in aging", just in front of the Open Science Room. Now you have two reasons to come to this corner! 😜

OSR Table Talk: Incentives for Open Science going on right now at the Open Science Room! With Andrew Zalesky, Annabel Chen, and Elvisha Dhamala! 🙂

Here's a list of content related to multi-echo fMRI at #OHBM2025 Let me know if there's anything to add. github.com/ME-ICA/ohbm-...

Did I mention there are Koalas? Yes, there are Koalas! Come to get your seal of Koality for your poster, or badge, or whatever!

There's also this aggregator from folks at @childmindinstitute.bsky.social childmindresearch.github.io/ohbm2025-dump/

At #OHBM2025 the Open Science Room has been squeezed and next year is at risk of being dramatically reduced/cut. If you like the OSR please consider signing/sharing this petition! chng.it/yjs4Bnyf9s @ohbmofficial.bsky.social @ohbmossig.bsky.social

“The same patch of cortex has multiple modes of connectivity all at the same time. You should not ignore this functional multiplicity. And you can make this error very consistently.” - Christian Beckmann

Sorry my math/stats workshop talk was a bit of a disaster as the videos didn't play :) but here it is anyway www.youtube.com/watch?v=nCfa...
