🧠How does the hierarchy of speech representations unfolds in the human brain?

Our latest work, led by @lauragwilliams.bsky.social, together with Alec Marantz and @davidpoeppel.bsky.social, is now out in PNAS:

Second, DINOv3 learns a representational hierarchy which corresponds to the spatial and temporal hierarchies in the brain.

First, we observe that, with training, DINOV3 learns representations that progressively align with those of the human brain.

Can self supervised learning help understand how the brain learns to see the world?

Our latest study, led by Josephine Raugel (FAIR, ENS), is now out:

We’re very happy to share 3 highlights of our Brain and AI team for #CCN2025 's week:

1. 🏆1st place for the Algonauts competition: paper, thtread and code below

2.🗣Keynote: Language in the Brain: 2025.ccneuro.org/k-and-t-lang...

3. 🚀Tutorial: Scale your decoding pipeline in the notebook

🚀 Dynadiff achieves state-of-the-art image reconstruction from time-resolved fMRI.
✂️ It significantly simplifies the training pipeline, eliminating complex multi-stage processes.
🧠 It uniquely reveals the precise evolution of visual representations in the brain.

Our latest brain-to-image decoding model is now available on HuggingFace:

"Dynadiff: Single-stage Decoding of Images from Continuously Evolving fMRI",

Together, these findings reveal the maturation of language representations in the developing brain and show that modern AI systems provide a promising tool to model the neural bases of language acquisition, and thus help both fundamental and clinical neuroscience.

The human brain is a remarkable learner:
A few million words suffice for children to acquire language.
Yet, the brain architecture underlying this unique ability remains poorly understood.

I'm very pleased to share our latest study:
