Cosyne invited me to give a long tutorial (4 hours!) on methods to quantify differences high-d neural recordings across animals, brain regions, deep neural nets, etc. The recording is up on youtube. I hope it inspires more research on this fundamental topic! www.youtube.com/watch?v=n44x...

My first time at #Cosyne2026 in beautiful Lisbon! I’ll be presenting my work on CorText (brain-language fusion) in the “AI for Interpretable Model Discovery in Neuroscience” workshop on Tuesday 17th (09:30). Looking forward! Reach out to me if to chat about neuroAI and brain foundation models 🧠

Our latest paper, “Visual language models show widespread visual deficits on neuropsychological tests”, is now out in Nature Machine Intelligence: www.nature.com/articles/s42... Non-paywalled version: arxiv.org/abs/2504.10786 Tweet thread below from first author @genetang.bsky.social...

1/7 Can infants recognise the world around them? 👶🧠 As part of the FOUNDCOG project, we scanned 134 awake infants using fMRI. Published today in Nature Neuroscience, our research reveals 2-month-old infants already possess complex visual representations in VVC that align with DNNs.

Interested in the latest advances in neuroscience (neural dynamics and internal models) and how they can be leveraged to build smarter, adaptive AI? ➡️ My first real solo piece 🖤🫶 @natneuro.nature.com rdcu.be/eWVmA

When and why do modular representations emerge in neural networks? @stefanofusi.bsky.social and I posted a preprint answering this question last year, and now it has been extensively revised, refocused, and generalized. Read more here: doi.org/10.1101/2024... (1/7)

🚨new work with the dream team @danakarca.bsky.social @loopyluppi.bsky.social @fatemehhadaeghi.bsky.social @stuartoldham.bsky.social @duncanastle.bsky.social We use game theory and show the brain is not optimally wired for communication and there’s more to its story: www.biorxiv.org/content/10.6...

Brains have many pathways / subnetworks but which principles underlie their formation? In our #NeurIPS paper lead by Jack Cook we identify biologically relevant inductive biases that create pathways in brain-like Mixture-of-Experts models🧵 #neuroskyence #compneuro #neuroAI arxiv.org/abs/2506.02813

In this piece for @thetransmitter.bsky.social, I argue that ecological neuroscience should leverage generative video and interactive models to simulate the world from animals' perspectives. The technological building blocks are almost here - we just need to align them for this application. 🧠🤖

Looking forward!

🚨 Out in Patterns! We asked ourselves, if complex neural dynamics like predictive remapping and allocentric coding can emerge from simple physical principles, in this case Energy Efficiency. Turns out they can! More information in the 🧵 below. I am super excited to see this one out in the wild.

Y’all are reading this paper in the wrong way. We love to trash dominant hypothesis, but we need to look for evidence against the manifold hypothesis elsewhere: This elegant work doesn't show neural dynamics are high D, nor that we should stop using PCA It’s quite the opposite! (thread)

What happens if you hook up an energy-efficiency optimising RNN on active vision input? It learns predictive remapping and path integration into allocentric scene coordinates. Now out in patterns: www.cell.com/patterns/ful...

6. The AI scientist took 45 minutes and $8.25 in LLM tokens to find a new tuning equation that fits the data better, and predicts the population code’s high-dimensional structure – even though we had only tasked it to model single-cell tuning.

New preprint led by @pablooyarzo.bsky.social together with @kohitij.bsky.social, Diego Vidaurre & Radek Cichy. Using EEG + fMRI, we show that when humans recognize images that feedforward CNNs fail on, the brain recruits cortex-wide recurrent resources. www.biorxiv.org/content/10.1... (1/n)

Introducing CorText: a framework that fuses brain data directly into a large language model, allowing for interactive neural readout using natural language. tl;dr: you can now chat with a brain scan 🧠💬 1/n

incredible Ada Lovelace quote highlighted in a talk by Steve Furber. She spells out the dream of computational neuroscience, 2 centuries ago. The sheer ambition 🤩

In other news, I am now a ✨ COXI ✨ (cognitive scientist in Osnabrück, Germany) www.uni-osnabrueck.de/en/campus-li... I'll be looking for PhD students & postdocs later this year, so watch this space if combining cognitive modelling, EEG & tFUS to study flexible cognition sounds exciting to you 🚀

Datasets like NSD & THINGS offer rich stimuli but often test a single task. After great conversations at #CCN2025 on multi-task studies & generalization in brains & models, I thought I would repost our perspective for those interested in this topic. We need multiple tasks!👉 doi.org/10.1038/s415...

That's a wrap for CCN2025 -- and so planning for CCN2026 in New York is starting today! Save travels to all participants and remember to fill out the feedback survey sent via email!

Looking for principles of neural organisation: should we ask what for or how come? Great kickoff discussions at the “Modeling the Physical Brain” CCN satellite event! #CCN2025 #topography

OK, time for a CCN runup thread. Let me tell you about all the lab’s projects present at CCN this year. #CCN2025

🚨 Finally out in Nature Machine Intelligence!! "Visual representations in the human brain are aligned with large language models" 🔗 www.nature.com/articles/s42...

🚨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

The final destination is an ontology not of a singular Universe, but of a pluriverse of viable, interacting maps. Reality, as we can know it, is not the silent, underlying territory. It is the noisy, dynamic, and ever-changing ecosystem composed of all these living, competing, and co-evolving maps.

The perspective that representational Universality and the ‘platonic representation hypothesis’ etc. are not addressing - multimodal / ANN-human alignment happens due to overlapping “Umwelts”, not due to all systems ultimately representing Reality™ (hot take?)

What makes visual processing in the brain so powerful and flexible? Very excited to share our new work where we started from SOTA models that accurately predict dynamic brain activity during hours of video watching, and investigated core computations underlying visual perception

Thank you everyone for your suggestions! This turned out to be a very useful resource. For those interested, you can see a compiled version of the suggestions from this thread here: tinyurl.com/kaz445jh (The wiki page will be updated as we find more resources.) 🧠🤖 , 🧠📈

This summer my lab's journal club somewhat unintentionally ended up reading papers on a theme of "more naturalistic computational neuroscience". I figured I'd share the list of papers here 🧵:

My paper with @stellalourenco.bsky.social ‬is now out in Science Advances! We found that children have robust object recognition abilities that surpass many ANNs. Models only outperformed kids when their training far exceeded what a child could experience in their lifetime doi.org/10.1126/scia...

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 arxiv.org/abs/2507.03168

How is high-level visual cortex organized? In a new preprint with @martinhebart.bsky.social & @kathadobs.bsky.social, we show that category-selective areas encode a rich, multidimensional feature space 🌈 www.biorxiv.org/content/10.1... #neuroskyence 🧵 1/n

What shapes the topography of high-level visual cortex? Excited to share a new pre-print addressing this question with connectivity-constrained interactive topographic networks, titled "Retinotopic scaffolding of high-level vision", w/ Marlene Behrmann & David Plaut. 🧵 ↓ 1/n

In this study, Lu et al. introduce All-Topographic Neural Networks (All-TNN) as a parsimonious model of the human visual cortex.

How can we model the emergence of topographical organisation in the brain and its impact on visual behaviour, using image-computable ‘behaving’ neural networks? 🧠We move beyond convolutions with All-TNNs…Now out in Nature Human Behaviour! #neuroai #neuroskyence

Energy efficiency is all you need.

A little late on the 🦋🚂, but happy to share a new(ish) preprint - the culmination of three years of postdoc with @tyrellturing.bsky.social and @apeyrache.bsky.social, and my first real foray into #NeuroAI as a tool to study the sleeping brain 🧠🟦: biorxiv.org/content/10.1... (1/🧵) c’est parti!
