Two weeks left to sign up for Re:vision! Let's figure out how well visual neuroscience findings replicate! Participants can: - become a coauthor on the paper - win cash prizes up to $2500 - use your replication to write a separate paper. Sign up now, it's super easy: re-vision-initiative.org

The GAC on World Models at #CCN2026 was SO good. Clearly very well prepared, clear division in proponents and skeptics, lots of concrete examples, beautiful synthesis at the end (and a poll on how audience opinions moved because of it). I learned a lot!

#CCN2026 make sure to check Luca’s poster - lots of opportunity to contribute to this exciting initiative!

(1/6) Do our visual neuroscience findings actually replicate? And do they generalize beyond the datasets they were found in? We've lauched re:vision, a community-driven initiative to answer these questions, and we are looking for scientistis to participate. re-vision-initiative.org

Feeling fortunate and excited to be able to return to #NYC and @nyu.edu to attend #CCN2026! I'll try to justify making a second transatlantic flight this year 🫣 by presenting no less than 3 times in total: 📣👇

CCN began at Columbia in 2017. As #CCN2026 returns to New York City, a special Back2NY event will feature a crowd-sourced panel discussion on how the community has grown, prior challenges, and future perspectives. Share your experiences in the community survey: 2026.ccneuro.org/back2ny/

Looking forward to this! Come and hear how you can participate!

Today at #VSS2026 we are introducing re:vision, a community driven replication/generalization initiative based on our newly released LAION-fMRI dataset. Come to the satellite at 2pm to learn more about it & why you may want to participate! The room Blue Heron is in the upstairs region of the lobby.

I'm proud to say we are releasing LAION-fMRI, a densely sampled 7T fMRI dataset of natural images, with very broad stimulus sampling for testing countless hypotheses and for deeply exploring brain representations. The dataset is now available at laion-fmri.hebartlab.com What does LAION-fMRI offer? 🧵

Looking forward to hear all the latest cool science, and to catch up with my science friends, former lab mates, former students, former supervisors, fellow conference organizers in the familiar beachy environment @vssmtg.bsky.social 📊🧠👁️🌴🏖️😎🍹!!!

Come and see our #ICLR2026 poster on our video model-human brain alignment study, led by two stellar students from the lab!

Check this out - yesterday I was on Dutch national television to discuss the intersection between #AI and the #brain, how we are addressing the fundamental questions there @uva.nl, and how we plan to tackle video understanding in my #NWO #VIDI project next! 🧠🤖📽️ npo.nl/start/afspel...

📣 New preprint by a stellar team 🤩 I’m most excited by “phase III” in the alignment time course, which is best captured by mid-layers of temporally integrating video models! While we do not directly compare with image-EEG (yet - will do so in the #VIDI) I suspect this is unique to video vision 🎥🔥

📢 New preprint, together with @sargechris.bsky.social! Building on @sargechris.bsky.social's previous work, we benchmark 100+ image and video models 🤖 on brain representational alignment, this time to EEG data of humans 🧠 watching videos! 🧵⬇️ www.biorxiv.org/content/10.1...

Pleased to share that our survey "Getting aligned on representational alignment" — on representational alignment across cognitive (neuro)science and machine learning — is now published in TMLR! openreview.net/forum?id=Hiq... Kudos to @sucholutsky.bsky.social @lukasmut.bsky.social for leading this!

Andrew Lampinen@lampinen.bsky.social

What is representational alignment? How can we use it to study or improve intelligent systems? What challenges might we face? In a new paper (arxiv.org/abs/2310.13018 ), we describe a framework that attempts to unify ideas from cognitive science, neuroscience and AI to address these questions. 1/2

Our exciting new preprint emphasizing the role of texture/local statistics in brain-DNN alignment (for EEG), online now!

Steven Scholte@neurosteven.bsky.social

🧠 New preprint: Why do deep neural networks predict brain responses so well? We find a striking dissociation: it’s not shared object recognition. Alignment is driven by sensitivity to texture-like local statistics. 📊 Study: n=57, 624k trials, 5 models doi.org/10.1101/2025...

Als zelfs een 'betrouwbaar' wetenschappelijk medium foutieve AI-gegenereerde informatie c.q. definities deelt als de waarheid. Lees vooral ook de mailwisseling met het medium onder het artikel.

I’ve had 40 birthdays so far, but this is the first one chairing a major international conference 👩‍💻! Thanks to the nearly 1000 attendees of #CCN2025 for coming to my birthday this year 😉
