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!

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? 🧵

LAION-fMRI - a 7T fMRI dataset of human vision

LAION-fMRI (LfMRI / LAION MRI dataset): 5 subjects, 25,052 launch-release natural images, 165 acquired 7T fMRI sessions with single-trial GLMsingle betas, retinotopy, localizers, and diffusion.

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

Curious about this AND attending #ICLR 26 🇧🇷? Come to our poster with @annewzonneveld.bsky.social 📆 Sat Apr 25, Poster session 5, 10:30-13:00 📍Pavillion 3 P3 - #1525, to learn how video models align with dynamic brain representations! 🕸️ sergeantchris.github.io/brain_dynami...

🚨 #CCN2026 Submission Updates! 🧠 The deadline for Generative Adversarial Collaborations (GACs), Keynote+Tutorials, and Community Events has been extended until March 31st! For more information on those event types, see the CCN 2026 website.

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...

Somewhat exhausted but very happily and proudly looking back at #CCN2025 & ready to pass the torch to NEW Amsterdam for #CCN2026 🥳Please fill out the survey 👇 to give input to the organizing team led by @neurograce.bsky.social and @toddgureckis.bsky.social @NYU!

Grace Lindsay@neurograce.bsky.social · 12mo ago

The rumors are true! #CCN2026 will be held at NYU. @toddgureckis.bsky.social and I will be executive-chairing. Get in touch if you want to be involved!

Final day of CCN 2025! 🎉 Ellie Pavlick opens with a keynote on neural compositionality, we have our last contributed talks and poster session, then Pieter Roelfsema gives the last keynote of the conference. Thread below 👇
