If you're interested in dynamical systems analysis for neuroscience, definitely check out @oliviercodol.bsky.social 's revised version of our RL paper! Very cool results in the new Fig 6, worth it regardless of if you saw our previous version or if it's all new. www.biorxiv.org/content/10.1...

Here is the results! I have mixed feeling about it! It's too textbook-y! 🧠

I rarely post things like this, but my friend’s mom needs urgent help for CAR-T cell therapy — it’s her only hope. Please take a second to visit the link and share it forward. It could make a real difference. 🙏 www.dimaan.ir/en

How does our brain excel at complex object recognition, yet get fooled by simple illusory contours? What unifying principle governs all Gestalt laws of perceptual organization? We may have an answer: integration of learned priors through feedback. New paper with @kenmiller.bsky.social! 🧵

Excited to share our new work with @engeltatiana.bsky.social! RNNs are often used to explore how the brain may solve specific tasks. We show that, depending on the architecture, RNNs find distinct circuit solutions, behaving differently when exposed to novel stimuli. www.nature.com/articles/s42...

Delighted to share our new paper, now out in PNAS! www.pnas.org/doi/10.1073/... "Hierarchical dynamic coding coordinates speech comprehension in the brain" with dream team @alecmarantz.bsky.social, @davidpoeppel.bsky.social, @jeanremiking.bsky.social Summary 👇 1/8

CogNeuroLanguage: new by @lauragwilliams.bsky.social & @jeanremiking.bsky.social (w Alec Marantz & me) shows how the brain maintains-updates continuously unfolding lang hierarchy during comprehension, anchoring ling theories to biological implementation www.pnas.org/doi/10.1073/... #neuroskyence

Dimensionality reduction usually loses information. - PCA loses the non-linear cycling. - t-SNE distorts the distances between the three populations -- Diffusion maps compress the early state cells and lose the cycling. Fig. 2e from nature.com/articles/s41...

My Microsoft Teams doesn't allow me to sign in as the software is outdated. The update button doesn't work, and I have to re-download the whole thing from their website. It reminds me of the time when I was using Windows, and for upgrading the version, I had to reinstall every single thing! 🪟

ok, imagine you have an oscillation that is not symmetric around 0 (small direct current shift) with some amplitude modulation, for instance with 1/f-dynamics. ➡️ then these 1/f-dynamics will show up in low frequency part of spectrum (red); in addition to around oscillation peak (yellow).

I have open positions for graduate students in my lab. If you’re interested in joining, please apply through the Mila form. I’m particularly interested in (thread below): 1/3 🧠🤖 #MLSky

The number of academic software tools in the world only grows with time, and learning new ones is daunting. Here, my postdoc @rgast.bsky.social spoke about PyRates, a model translator that lets you study dynamical systems with a whole suite of tools built in Python, Julia, Matlab, and Fortran.

New paper out with David Pascucci! We hash out our opposing views on the probabilistic nature of perception and cognition are probabilistic. It was a very rewarding undertaking: the challenge of disagreement coupled with the satisfaction some consensus. www.sciencedirect.com/science/arti...

When part of a word is replaced by noise, humans still hear the whole word. How do brains do this? New from Meliza group in @natcomms.nature.com Le et al. study this in zebra finches, a model system for vocal learning www.nature.com/articles/s41... #prattle 💬 #neuroskyence 1/5

🎉 "High-dimensional neuronal activity from low-dimensional latent dynamics: a solvable model" will be presented as an oral at #NeurIPS2025 🎉 Feeling very grateful that reviewers and chairs appreciated concise mathematical explanations, in this age of big models. www.biorxiv.org/content/10.1... 1/2

New in @pnas.org: doi.org/10.1073/pnas... We study how humans explore a 61-state environment with a stochastic region that mimics a “noisy-TV.” Results: Participants keep exploring the stochastic part even when it’s unhelpful, and novelty-seeking best explains this behavior. #cogsci #neuroskyence

🚨 New preprint! “A Computational Perspective on the No-Strong-Loops Principle in Brain Networks” www.biorxiv.org/content/10.1... Over the past 3 years, we’ve been investigating why cortical networks avoid strong reciprocal loops — and what this means for computation.

I’m super excited to finally put my recent work with @behrenstimb.bsky.social on bioRxiv, where we develop a new mechanistic theory of how PFC structures adaptive behaviour using attractor dynamics in space and time! www.biorxiv.org/content/10.1...

A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue. The effect presumably comes from the absence of S-cones in the fovea. From Hinnerk Schulz-Hildebrandt: arxiv.org/pdf/2509.115...

New preprint! What happens if you add neuromodulation to spiking neural networks and let them go wild with it? TLDR: it can improve performance especially in challenging sensory processing tasks. Explainer thread below. 🤖🧠🧪 www.biorxiv.org/content/10.1...

🚨New preprint alert! The thalamus has long been seen as a relay of sensory signals to cortex. But could it also generate its own structured activity? Our study explores this question in the head-direction (HD) system. Some explanation 🧵👇 1/13 www.biorxiv.org/content/10.1...

Neural entrainment by speech in human auditory cortex revealed by intracranial recordings www.sciencedirect.com/science/arti... 12 people had intracranial electrodes & listened to natural speech oscillatory -> speech edge induced activity persisted after evoked responses thus ...neural entrainment?

In today's Generative AI lecture, we cover Vision Transformers (as well as the broader notion of Encoder-Only Transformers). We also explain the historical throughline to some of these ideas, inspired by Nobel-prize-winning observations in neuroscience!

All at once!
