open.substack.comWhen an audio AI Model Play 🧠 Dress-UpThis really is about fine-tuning an audio artificial network to align representations with human brain data, and seeing what happened next

21 Nov 2025

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...

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.

Hao-Ting Wang@haotingwang.bsky.social

On November 26th noon ET, @complexbrains.bsky.social will present her talk titled " Aligning Brains and Language Models: Toward a NeuroAI Framework for Brain-Grounded Language Understanding". The project combined @cneuromod.ca dataset 🧠🧑‍🤝‍🧑 and AI 🤖.

Brain–AI alignment can reveal exciting similarities in representations. Our Super Mario Bros. experiment demonstrates an important caveat: alignment can be very brittle. 1/🧵

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/

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/

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!

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/🧵

The result? Nearly 1000 hours of task fMRI from 6 subjects (mostly 5). We're releasing experiments slowly, focusing on quality checks and well-documented derivatives for reuse. 5/6 participants made their data fully open (CC0), thanks to @conp-pcno.bsky.social

Meet us at @cogcompneuro.bsky.social in Amsterdam! The team will be there, including @jaboyle.bsky.social (project lead), Basile Pinsard (data manager), and @lune-bellec.bsky.social (founder). #CCN2025
