The 2nd CogBases Workshop is this 4 & 5 Nov at Institut Pasteur! We'll discuss the latest in open science methods for analysing brain imaging data. Registration free, but mandatory neuroanatomy.github.io/cogbases-2025/ @k4tj4.bsky.social @cmaumet.bsky.social @bthirion.bsky.social @demw.bsky.social

OpenNeuro @openneuro.bsky.social just hit a huge milestone: 1500 datasets! Congrats to the team on making this project so successful over the last 7 years.

The Biological Psychiatry family of journals is now officially on Bluesky! Follow us for the latest research in psychiatric neuroscience, cognitive neuroimaging, and global open science from our three leading journals.

Many brain imaging “biomarkers” for autism have been proposed. Most aim for balanced accuracy (matching sensivity/specificity) on datasets where cases and controls are split 50/50. 1/🧵

"A murder of butterflies" has a nice ring to it.

This year at #CCN25 we showed the importance of OOD evaluation to adjudicate between brain models. Our results demonstrate these trivial but key facts : - high encoding accuracy ≠ functional convergence - human brain ≠ NES console ≠ 4-layers CNN - videogames are cool w/ @lune-bellec.bsky.social 🙌

Excited to co-organize our NeurIPS 2025 workshop on Foundation Models for the Brain and Body! We welcome work across ML, neuroscience, and biosignals — from new approaches to large-scale models. Submit your paper or demo! 🧠 🧪 🦾

This is why I think the platonic rep hypothesis doesn’t apply to brain-ANN alignment, since most existing (functional?) models are implicitly or explicitly trained to mimic humans. The assumption of PRH is that the networks are trained independently which doesn’t hold in brain-ANN comparisons.

Just wrapped up my first real foray into analyzing brain data at Brainhack School 2025 a couple weeks ago 🧠💻 I focused on comparing fMRI techniques on a single subject, using fear as a case study. school-brainhack.github.io/project/many...

Hi friends, I have news! Giga connectome, a BIDS app for post-fMRIPrep connectome extraction, is now in @joss-openjournals.bsky.social 🎉 Thanks to @remigau.bsky.social, @clarken.bsky.social, Quentin Dessain, and @lune-bellec.bsky.social for working on this together

Text-to-LoRA: Instant Transformer Adaption arxiv.org/abs/2506.06105 Generative models can now produce text, image, video. They should also be able to generate models! We trained a Hypernetwork to generate new task-specific LoRA models by simply giving it a description of the task as a text prompt.

AI may still need some neuroscience: "AI systems will not acquire the flexibility and adaptability of human intelligence until they can actually learn like humans do, shining brightly with their own light rather than observing a shadow from ours." 🧠🤖 sergeylevine.substack.com/p/language-m...

New preprint! 🧠🤖 How do we build neural decoders that are: ⚡️ fast enough for real-time use 🎯 accurate across diverse tasks 🌍 generalizable to new sessions, subjects, and even species? We present POSSM, a hybrid SSM architecture that optimizes for all three of these axes! 🧵1/7

More evidence on the fact the fact that fine tuning AI sound processing models reshapes representations in a meaningful way. Perhaps unsurprising- it's just distillation of a big model in a small model, but i often get a lot of skepticism on this idea. arxiv.org/abs/2506.038...

🧩 The dream: FAIR models and data. Only standards can solve the MxN problem, and this session is exactly about that. And we wrap up today’s workshops with a group reflection: Why are FAIR resources essential for scientific progress?

#neuroAI preprint alert: studying the convergence of multimodal AI features with brain activity during movie watching. Notably identifies brain areas where multimodal features outperform unimodal stimuli representations. And it uses @cneuromod.ca 's movie10 dataset :) arxiv.org/abs/2505.20027

Our lab is present at #VSS2025, so let me highlight some of the things we have been up to with a talk and three posters. Would love to see you around! 🧵

Because I have opened a BlueSky window and am procrastinating on reading final papers, let me also share what this spring has been like from my corner of the academic world.

Our newest paper from a brilliant undergraduate researcher (now a PhD student at McGill!) Nate Roy. We use network control theory to show how dynamics shift after traumatic brain injury! A great collaborative team. doi.org/10.1016/j.ni...

If you haven't used Claude Code yet, you should - it's absolutely amazing! Yesterday I built an app that uses 4 LLM APIs (openai, anthropic, google, and together.ai) to perform an automated meta-review of a paper - using only the Claude interface, never touching code! github.com/poldrack/ai-...

I love the work, not only because it speed up FIC models a lot, but also how it saves poor students from grad student descent 🤣🤣

Chronic #pain involves changes in multiple brain systems for nociception, threat, and reward. What self-management practices can help us live with or even reverse these changes? Cognitive, behavioral, and #digitalhealth strategies can help! New review in Lancet: authors.elsevier.com/a/1l5%7EfV-4...
