A glimpse at what #NeuroAI brain models might enable: a topographic vision model predicts stimulation patterns that steer complex object recognition behavior in primates. This could be a key 'software' component for visual prosthetic hardware 🧠🤖🧪

I've been arguing that #NeuroAI should model the brain in health *and* in disease -- very excited to share a first step from Melika Honarmand: inducing dyslexia in vision-language-models via targeted perturbations of visual-word-form units (analogous to human VWFA) 🧠🤖🧪 arxiv.org/abs/2509.24597

🚨 New preprint alert! 🧠🤖 We propose a theory of how learning curriculum affects generalization through neural population dimensionality. Learning curriculum is a determining factor of neural dimensionality - where you start from determines where you end up. 🧠📈 A 🧵: tinyurl.com/yr8tawj3

📢🦋 Our paper ‘Global selection on insect antipredator coloration’ is out and featured on the cover of @science.org We ran a huge experiment to find out how ecological context favours camouflage and warning colouration as antipredator strategies. 1/6 www.science.org/doi/10.1126/...

Very much look forward to our workshop (co-organized with @armanbehrad.bsky.social) today with a great lineup of speakers who combine a wide spectrum of approaches and methods to have a joint definition of brain-behavior state! bernstein-network.de/bernstein-co... #BernsteinConference

What defines a brain state? 🧠 If you are also interested in answering this question, join us in "Toward a joint definition of neural-behavioral states", #BernsteinConference full-day workshop, Co-orgnized by @neuroprinciplist.bsky.social and I. (1/4)

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

Proud of my PhD student @rodento.bsky.social for her first study on the effect of environmental structure on social phenotype of desert locusts. An amazing collaboration with @einatcouzin.bsky.social , who got me to work on locusts. You want to know more: www.biorxiv.org/content/10.1...

How is valence computed in the brain? Check out our new preprint about a single cell that integrates excitatory and inhibitory input across modalities according to valence and impacts behavioral decisions. An exciting collaboration across many labs. Enjoy reading! www.biorxiv.org/content/10.1...

Very excited and proud to share my postdoctoral research with @neurrriot.bsky.social looking at the context-specific encoding of social behavior 💃🕺 in hormone-sensitive, large-scale brain networks in mice! www.biorxiv.org/content/10.1... #neuroskyence #compneurosky 🧪 1/12

The brain is incredibly densely connected. Human cerebral cortex may have as many as *one trillion* connections. Most of those cortical connections are recurrent, inside each area. What do they do? New paper from me in Annual Reviews: 🧪 🧠📈 1/ www.annualreviews.org/content/jour...

Oops, wrong time in the original post! It will be 15:30 CET 😉

In our Learning Club @cmc-lab.bsky.social today (Sep 25, Thu, 2pm CET), @dengpan.bsky.social will tell us about his recent paper (👇) [joint work w/ Rushworth lab]. Want to attend, send an empty email to [email protected] to get the link!

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...

I've been waiting some years to make this joke and now it’s real: I conned somebody into giving me a faculty job! I’m starting as a W1 Tenure-Track Professor at Goethe University Frankfurt in a week (lol), in the Faculty of CS and Math and I'm recruiting PhD students 🤗

New work from the lab, mismatch responses consistent with spatial but not temporal predictive coding theory.

(edited repost) Thrilled to see our computational work on adaptive shaping of behavior (we call it outcome-based curriculum learning) in PLoS Comp Biol! @wl-tong.bsky.social, @gautamreddy.bsky.social & I formalize curricula in any RL task that can be framed as sequential simple-to-complex behavior.

This is one of the most outstanding examples of circuit understanding I've seen in a long time. The unification of theory and experiment is beautiful. When Malcolm presented this in my lab, the audience was cheering at the end, and one person shouted (non-ironically) "You did it!"

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 paper on precise tool use learning in carrion crows @currentbiology.bsky.social. We show that—like New Caledonian crows—expert carrion crows pay close attention to the working end of their tool, suggesting tool integration into their peripersonal space. 🧵 & vids! 👇 www.cell.com/current-biol...

"Sleep, like aging, may be an inescapable consequence of aerobic metabolism." Really enjoyed this thought-provoking paper 🧠💤🪰 - congrats to @rafsarnataro.bsky.social and team on this impressive work! No wonder the Krebs cycle always put me to sleep 😅 #neuroskyence

Stoked to see this paper finally out! It answers two big questions: where visual objects are encoded in the brain, and how head-direction cells get oriented using visual landmarks. Super fun collaboration with @mace-lab.bsky.social and Stuart Trenholm. www.science.org/doi/10.1126/...

What determines where specialisation for sensory information occurs in the cortex? We observe a spatial competition between primary sensory areas and the Default Mode Network, using our new Spatial Component Decomposition method.

Something exciting just left the gym -- meet Arnold the first generalist musculoskeletal control policy! The human body has 600+ muscles, yet we seamlessly coordinate them for everything from whispering a syllable to felling a forrest. How? www.arxiv.org/abs/2508.18066

Adaptive learning is coordinated across behaviour, time and neurobiology (from synapses and dendrites, to astrocytes and the systems level). If you’ve ever wondered how noradrenaline helps shape these multiscale learning processes, you might like this: www.cell.com/trends/cogni...

New #NeuroAI #compneurosky preprint! To better understand how target-directed learning works in the brain, we sought to engineer an artificial neural network capable of solving complex image classification tasks that comprises only experimentally-supported biological building blocks. (1/15)

Is the hippocampus best understood in term of discrete subfields or functional gradients? Functional gradients are recapitulated within each hippocampal subfield, supporting a role for both discrete & continuously changing computations. Neat work by Bouffard, @barense.bsky.social, & Moscovitch!

Here's a set of new results from my lab asking how the brain combines different ideas (concepts)! Now in press at J of Cog Neuro, we looked at how semantic composition (combining different concepts together) shapes brain activity. Preprint here: www.biorxiv.org/content/10.1... #neuroskyence

Happy to share our new preprint. We found that brain adaptively switches between relational and item-based coding strategies based on the structure of memory contents. @doellerlab.bsky.social www.biorxiv.org/content/10.1...
