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

Honored & looking forward to give this lecture tomorrow @ucl-neuroai.bsky.social!
unireps.bsky.social
🧠✨ How closely do AI models mirror the human brain?
Join us for @irisgroen.bsky.social’s talk: “Alignment of visual representations in AI and human brains: beyond object recognition”

📢 10 days left to submit to the Data on the Brain & Mind Workshop at #NeurIPS2025!

📝 Call for:
• Findings (4 or 8 pages)
• Tutorials

If you’re submitting to ICLR or NeurIPS, consider submitting here too—and highlight how to use a cog neuro dataset in our tutorial track!

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!
neurograce.bsky.social
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!

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 😉

The moment we've all been waiting for— #CCN2025 is HERE! Today we start with satellite events, and tomorrow the main conference begins in Amsterdam! We'll be sharing daily updates about each day's program, so follow the CCN account to stay in the loop. Can't wait to see everyone!

All together a diverse set of studies, grouped around the central question of how human-aligned deep neural networks are, and how we can use them to learn more about the brain! Looking forward to discuss, hearing your thoughts, and to an exciting and immersive week full of science ahead 😀🧠🤖🧑‍💻📈📊🥳

Finally, Otto Márton, an MSc student in the lab, shows small but consistent benefits of DNNs with hyperbolic geometry for capturing human representations of objects in behavior (using THINGS) and the brain (THINGS-EEG and NSD) 2025.ccneuro.org/poster/?id=b... Poster C109, 14:00-17:00.

On Friday, niklasmuller.bsky.social shows that estimating population receptive fields (pRF) using DNN feature maps but without assuming a Gaussian pRF shape yields better predictions of THINGS ephys data, uncovering surprising pRF geometries! 2025.ccneuro.org/poster/?id=1...

Next, on Wednesday, another Proceedings paper by Amber Brands, showing that PredNet, a well-known predictive coding DNN, does not exhibit signatures of short-term adaptation that are ubiquitous in the brain, such as repetition suppression 2025.ccneuro.org/poster/?id=y... Poster B131, 13:00-16:00

In the EEG study, accepted as Proceedings, we replicate these findings in the temporal domain, showing unique processing of locomotive affordances around 200 ms, which is independent of object or GIST features, and not well captured by DNNs 2025.ccneuro.org/poster/?id=6... Poster A69, 13:30-16:30

And in a third Tuesday poster, Clemens Bartnik presents very neat EEG results complementing his recent PNAS paper that used fMRI to demonstrate unique representations of locomotive affordance perception in the human brain www.pnas.org/doi/suppl/10...

Also on Tuesday,
@annewzonneveld.bsky.social
reports whether video-DNNs exhibit temporal straightening, a computational motif found in brains thought to aid future state prediction. Spoiler: some CNNs straighten, Transformers do not! 2025.ccneuro.org/poster/?id=E... Poster A152, 13:30-16:30

On her CCN poster, Christina zooms in on a specific set of multi-pathway video-DNN that separately compute motion features and image features, to explore alignment of static vs. dynamic representations with cortical processing streams 2025.ccneuro.org/poster/?id=s... Poster A154, 13:30-16:30

On Tuesday,
@sargechris.bsky.social
will present a follow-up on her earlier ICLR paper (openreview.net/pdf?id=LM4PY...), where we performed large-scale benchmarking of video-DNNs agains the BOLD Moments fMRI dataset, to see how well such models are representationally aligned with the human brain;

After preparing for a full year together with @neurosteven.bsky.social and all other amazing organizers
of @cogcompneuro.bsky.social, #CCN2025 is finally here!

While I'm proud of the entire program we put together, I'd now like to highlight my own lab's contributions, 6 posters total:

Or, blend in with the Amsterdam locals and rent a bicycle for the duration of the conference 🚲😀
