The Courtois project on Neural Modelling (cneuromod) aims at training artificial neural networks to mimic extensive experimental data on individual human brain activity and behaviour.

Brain–AI alignment can reveal exciting similarities in representations.
Our Super Mario Bros. experiment demonstrates an important caveat: alignment can be very brittle. 1/🧵
Our very own Isil Bilgin will share some updates on her work with Leila Wehbe and @lune-bellec.bsky.social to create brain-aligned language models by fine-tuning LLAMA-7B to produce brain-like embeddings.
We showed that the raw memory content of the NES console aligned with brain activity about as well as a convolutional neural network trained with RL.
And the brain is obviously not a NES. 2/

Importantly, In both cases, alignment collapsed on new game levels. This “demonstration ad absurdum” shows that meaningful brain alignment must be robust and generalize across conditions. 3/
CNeuroMod is now on substack, and our first post highlights a new study showing that a tiny 2M-parameter audio model can be meaningfully fine-tuned on an individual brain with benefits for downstream AI tasks. open.substack.com/pub/cneuromo...
This was presented by Yann Harel and coll. at poster #148 at @cogcompneuro.bsky.social .

In 2019, the CNeuroMod team and 6 participants began a massive data collection journey: twice-weekly MRI scans for most of 5 years. Data collection is now complete! 1/🧵
We’d love your feedback on BERG (github.com/gifale95/BERG): pretrained encoding models + a Python toolkit for generating in silico neural responses for in silico experimentation. Your input will make BERG more useful and reliable!

Very much looking forward to #CCN2025! Would love to see you at our lab's talks and posters, and meet me at the panel discussion in the Algonauts session on Wednesday!
