🧵(1/n) I'm thrilled to announce that I published my very first! pre-print on BioRxiv. This work was co-supervised by Wilson Truccolo and Timothée Proix @ndlab.bsky.social. www.biorxiv.org/content/10.1... 🧠🧪 #compneuro

Where does the six-fold grid signal (HexMod) in human fMRI come from? Our preprint points to firing rate adaptation in grid cells 🧵 1/7 Work with Misun Kim @zilong-ji.bsky.social Daniel Bush @caswell.bsky.social @neilburgess10.bsky.social, on bioRxiv: doi.org/10.64898/202...

New blog post: "we should resist ... using journal publication record as a key indicator of applicant suitability, because it’s a system that shifts costs from the rich to the poor, slows down scientific progress as a whole, and bakes in discrimination" thesamovar.github.io/zavarka/hiri...

A Relational Code for Objects in Primate Frontal Cortex www.biorxiv.org/content/10.6... "Represents not only where objects are, but also how they are arranged with respect to one another." It's so rare to see studies of multi-object perception! Does neuroscience have a single object bias?🤔

Mandlebrot's coastline paradox reframes measurement as a joint property of an object and its ruler. Here we ask how observational resolution shapes the apparent structure of neural computation. Read here 👇📜 arxiv.org/abs/2610.19487

Super proud of many things about this work by the amazing @kristorpjensen.bsky.social. The work is one of my favourite things ever from the lab. Also super proud of Kris for choosing to send it to @elife.bsky.social - we get to see Kris explain every figure! elifesciences.org/articles/109...

Mind blown by this book I’m reading. Many probably know that rodents implanted with electrodes in some brain regions will vigorously stimulate. Here’s the complex history of that type of thing in humans, often with benevolent intent but clearly unethical in some cases. nautil.us/can-you-over...

Reminder: we're looking for 2 postdocs and 1 PhD student to join us in Barcelona to explore the computational mechanisms of perception 👁️👂🧠. With a flexible blend of theory & experiments. Please spread the word 🙏

How much representational diversity exists around a trained network? A lot, it turns out! Moving a ViT’s weights by 1.3% while preserving its predictions, its representations end up less similar to the original than a random-init ViT’s ‼️ New paper: Hessian Null Space Continuation (HNC) 💫🧵 (1/12)

Too many neuro preprints to keep track of, so I made a monthly ranking of the most-read ones on bioRxiv. Not a measure of quality, just what people are reading. Here's the fresh ranking for September: robertodf.github.io/biorxiv-top/

Some exciting new work: arxiv.org/abs/2610.12426 On X, I shared some explanation and broader thoughts: x.com/d_g_clark/st... Additionally, an X user made an extremely good 3Blue1Brown-style explainer video. Each step is described accurately and beautifully: x.com/nachilos_/st...

Excited to share that my postdoc work with Timothée Proix @ndlab.bsky.social is now in Nature Communications!🎉 Recording from 624 human neurons, we show that semantic predictions realign phonetic population activity—revealing how meaning feeds back to reshape speech-sound processing. Thread 1/6 👇

Excited to share our new paper in Nature Communications! 🎉 Recording neurons in human temporal cortex, we found that speech sounds and word meaning are both encoded in neural manifolds, and that speech sounds line up in time with word meaning, a signature of top-down prediction. 🧵

Conspiracy theory: Who/what placed m-dashes in the articles and texts published before 2022?

Our paper just dropped in the Journal of Neuroscience! How does the brain segment continuous audio into distinct units for speech perception? We show that the auditory forebrain actively decodes temporal landmarks to make this happen. www.jneurosci.org/content/earl... #Neuroscience

What kind of dynamics underlie sequence working memory? In the last project of my PhD we developed and analysed RNNs fitted to multi-session single-unit data of macaques. Now out on: www.biorxiv.org/content/10.6... With @jakhmack.bsky.social and data from Chen et al., Neuron 2024. [1/4]

I was reflecting on how many random contingencies went into creating the current accelerating AI moment and had Opus 5.5 put together a video, inspired by old science show Connections, to try and point out how a series of initially unrelated ideas led to the moment we are in now.

New preprint! 🧠 How do RNNs learn abstract rules from sequences, independent of specific stimuli? By Vezha Boboeva, with Alberto Pezzotta & George Dimitriadis "From sequences to schemas: low-rank recurrent dynamics underlie abstract relational representations" www.biorxiv.org/content/10.6...

Our review on language networks and neuromodulation is finally out! 🎉 We propose the Interacting Language Network (ILN), arguing that neuromodulation for language disorders should target distributed networks rather than isolated regions. doi.org/10.1016/j.ne...

Come and meet the Neural Reckoners at #BernsteinConference next week. I'll be talking about our recent work on neuromodulation at the satellite workshop below, and we have some posters.

New preprint 🧠🗣️ We recorded intracranial activity while people told stories freely. The brain commits to sentence structure early: syntactic depth and core categories (nouns, verbs) are encoded ~1s before articulation, while adjectives and adverbs are specified only ~0.5s out. Check it out!

Excited to share that I'll be starting as a junior professor and Emmy Noether awardee at the University of Göttingen this October! 🥳 🚀 I'll be hiring #phd students and #postdoc across #machinelearning, #neuroscience and #cogsci: modirlab.github.io/open-positio... Please spread the word! 🙏

Study finds that when a network with low-dimensional structure receives outside input or is perturbed by noise, it can produce either high- or low-dimensional responses depending on the finer structure of the network and its input. Read the study: https://go.aps.org/4fT3NLA

How do you "see" with electric eyes? How does collective behavior emerge from individual interactions? Nocturnal weakly electric fish evolved to do this, but studying naturalistic social behavior is very hard. Our solution? Virtual 'fish' 🤖🐟⚡ 📄 arxiv.org/abs/2511.08436

If an action results in error, each neuron requires an individualized teaching signal that guides change in its output. This is the credit assignment problem of learning. Are there neurons in the brain that can compute such a sophisticated teaching signal? Yes. www.biorxiv.org/content/10.6...

Happy Monday! Come learn how jellyfish swim. In a review led by fluid dynamics maestro Alex Hoover, we outline how neuromechanical modeling will help us understand how modulation of neural activity allows jellyfish to jet and pirouette through fluids www.sciencedirect.com/science/arti...

new preprint! 🥳 we investigated the encoding of syntax and probability in cortical activity recorded with ECoG 🧠, and, it turns out: high-frequency cortical activity represents both features - side-by-side 🙌, and in interaction 🤝. www.biorxiv.org/content/10.6... (thread to follow soon)

Most of the statistical tests you learned in stats class — t-test, ANOVA, correlation — are actually special cases of a single thing: linear regression. Ch 7 of Experimentology argues that thinking in models, not tests, is more flexible and a better foundation for theory. 🧵 experimentology.io
