🚨New paper🚨

Neural manifolds went from a niche-y word to an ubiquitous term in systems neuro thanks to many interesting findings across fields. But like with any emerging term, people use it very differently.

Here, we clarify our take on the term, and review key findings & challenges rdcu.be/ex8hW

Do you study neural systems with feedback at different temporal-, spatial-, hierarchical-, data-, or computational- scales? Have you submitted your abstract to the "Neurocybernetics at Scale" symposium?
Due to multiple requests, new abstract submission deadline is 18 July! #AI4Science #cybernetics

NeurReps is back for its 4th edition at NeurIPS 2025! Stay tuned for updates!

Exciting new preprint from the lab: “Adopting a human developmental visual diet yields robust, shape-based AI vision”. A most wonderful case where brain inspiration massively improved AI solutions.

Work with @zejinlu.bsky.social @sushrutthorat.bsky.social and Radek Cichy

NeurReps 2025 is starting to take shape! If you're interested in serving in the Program Committee 👇

Excited to share our latest study! 🧠✨ We reveal how non-direction-selective retinal ganglion cells encode motion beyond their receptive field, relaying the unconventional signals to the brain. A new insight into multimodal neurons in visual processing!

I dream of a future in which single neuron dynamics ➡️ circuit motifs ➡️ distributed computations are taught as part of the same curriculum and no one bats an eye and everyone is happy.

Adaptation shapes the representational geometry in mouse V1 to efficiently encode the environment Sensory adaptation dynamically changes neural responses as a function of previous stimuli, profoundly impacting perception. The response changes induced by adaptation have been characterized in detail...

New results! Visual adaptation changes the geometry of V1 population activity: frequent stimuli elicit smaller responses but become more discriminable. Similar results are seen in ANNs trained with metabolic constraints, suggesting these changes emerge from efficient coding. bit.ly/3VJHXRn

Created a starter pack of neuroscience in/from Paris.

Let me know if you want to be added (the 'from' can include those not in Paris anymore) or just tap in if you want to know what we're talking about!

I'll be in Vancouver for the next week @neuripsconf.bsky.social. Who will I see there? Happy to chat about vision, comp neuro, equivariance, learning representations.

In case you share my interests, consider joining our workshop @neurreps.bsky.social on Dec 14th 🧠

Advancing Neuromotor Interfaces by Open Sourcing Surface Electromyography (sEMG) Datasets for Pose Estimation and Surface Typing We’re releasing emg2qwerty and emg2pose—two large datasets and benchmarks for sEMG-based typing and pose estimation, as part of the NeurIPS 2024 Datasets and Benchmarks track.

New 716 hour EMG dataset just dropped ✨ ai.meta.com/blog/open-so...

Excited to present "Latent Functional Maps" at #NeurIPS !

We show how neural models can be aligned by matching function spaces on representation manifolds, providing a unified framework for model comparison, matching, and information transfer.
