Does predictive coding work in SPACE or in TIME? Most neuroscientists assume TIME, i.e. neurons predict their future sensory inputs. We show that in visual cortex predictive coding actually works across SPACE, just like the original Rao+Ballard theory #neuroscience www.biorxiv.org/cgi/content/...

Why does AI sometimes fail to generalize, and what might help? In a new paper (arxiv.org/abs/2509.16189), we highlight the latent learning gap — which unifies findings from language modeling to agent navigation — and suggest that episodic memory complements parametric learning to bridge it. Thread:

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...

Anyone using a lightweight #PDFreader on #iOS26? #Apple’s #Preview on #iOS is kind of heavy. The UI elements are always visible and never auto-hide, which gets annoying. I’m looking for something minimal: must support search, annotation, clean/distraction-free UI. Any recommendations?

How does the brain decide? 🧠 Our new @nature.com paper shows that neural activity switches from an 'evidence gathering' to a 'commitment' state at a precise moment we call nTc. After nTc, new evidence is ignored, revealing a neural marker for the instant when the mind is made up. rdcu.be/eGUrv

Hey #neuroskyence #compneurosky I made this interactive tool for showing the phase planes of 2D neuron models to studs! Have fun :) github.com/JuliaSNN/Com...

My talk at the WWTNS is now online! In it, I explore how both random processes and Hebbian learning shape representational drift: www.youtube.com/watch?v=WH4P... In the end I raise the question: How can neuronal activities change while representational similarity is preserved? 🧠🧪

Reconstructing long-range axons from dense brain images is tough. This study introduces a novel method that separates axon identification from global statistical rules, showing big improvements over existing tools for mapping neuronal projections. buff.ly/6ajguDI

Have a great weekend ✌️ #Sunset and #reflections at the @dzne.science#Sunset#reflections#DZNE 🌅

Today, we had a great #iBehave lecture by Yaniv Ziv at @dzne.science. He presented his work on #RepresentationalDrift in the #hippocampus, studying #PopulationDynamics of freely moving mice 💪 Great insights into how neuronal codes evolve over time! @ibehave.bsky.social#iBehave#RepresentationalDrift#hippocampus#PopulationDynamics#neuroscience 🧪 #CompNeuro

Happy to share our new paper with Mathilde Nordlund and Julie Koenig out @currentbiology.bsky.social. We used virtual reality in mice to study hippocampal distance coding. Our results suggest a primary contribution of grid cells to distance over cue-dependent place cell coding. shorturl.at/63yFo

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...

New study by Johnston, Kirschhock & Nieder: Carrion #crows 🐦‍⬛ estimate time 🕠 using abstract magnitude coding in the nidopallium caudolaterale (avian “prefrontal” #cortex). NCL neurons, tuned to 1.5, 3 & 6 s, predicted duration. Shows sophisticated timing – even w/o a #neocortex 🧠 #Neuroscience 🧪

Björn Kampa, Willem Wybo and I have organized an exciting symposium at the upcomig #BernsteinConference: bernstein-network.de/bernstein-co... Everything about Dendrites: Check it out!

Application is open! Come join us and our fantastic line-up of speakers next year in March in Bonn!

The Bernstein conference is approaching, and we're thrilled about the incredible contributions coming our way! Don't miss the workshop 'Neural architectures in action: Linking structure to computation across scales,' which includes various contributions including NEST! tinyurl.com/bernsteinarc...

“Everyone knows” what an autoencoder is… but there's an important complementary picture missing from most introductory material. In short: we emphasize how autoencoders are implemented—but not always what they represent (and some of the implications of that representation).🧵

🧠 New preprint by Ruff et al. (2025): #NeuralPopulation formatting matters for function. In monkeys, #MT encodes motion & reward separately, #dlPFC integrates them. An #RNN predicted, and microstimulation confirmed, distinct #behavioral impacts. #Neuroscience 🧪 #CompNeuro 💻#DecisionMaking

Just a reminder to check for your name in this list of books that OpenAI trained from. If your name is there, they probably owe you several thousand dollars. OpenAI cried that if everyone eligible author files, the company will go bankrupt, so I'm alerting every author I have ever spoken to.

🧠 “Correlation ≠ causation”? This new study put it to the test: activity in posterior parietal #cortex not only correlates with navigation choices, it is causal. Using a #BrainMachineInterface, mice could steer solely from these signals. #Neuroscience #SystemsNeuro #Causality #DecisionMaking #BMI

Complementary approach: simultaneous recordings allow analyses to see who leads and who lags. Among other results stemming from simultaneous recordings, in this preprint we show that during decision-making, frontal cortices and striatum lead, other regions lag. doi.org/10.1101/2024...

New paper on covariant #neuromorphic networks! We're connecting decades of work in computer vision with decades of work in spiking networks. And, in an event-based vision task against regular ANNs of similar complexity, spiking networks are doing much, much better! www.nature.com/articles/s41...

🧠How can brains learn new tasks w/o forgetting old ones? Barry, Gerstner & Bellec propose #GateON, a neuro-inspired learning rule: neurons become context-selective & #plasticity can be frozen or unfrozen. Balances #memory & #flexibility, avoiding #CatastrophicForgetting in #AI models. #CompNeuro🧪

🖥 @fzj-jsc.bsky.social just inaugurated #JUPITER, #Europe’s first #exascale #supercomputer. Must be fun to run models on that thing. Finally scaling #NeuralDynamics 🧪🧮 by population size and complexity without melting your workstation 🤪 🌍 https://www.fz-juelich.de/en/jupiter

🧠 Sakelaris & Riecke (2025) model structural #plasticity in the #OlfactoryBulb and show that fast #learning and slow #forgetting is enabled by the maturation of adult-born #neurons from #neurogenesis, with transiently enhanced plasticity, excitability and #apoptosis #neuroscience 🧪 #olfaction 👃

🇨🇭 #Switzerland just released the first truly #OpenSource #LLM: #Apertus. Trained on ~15T tokens across 1,000+ languages (40% non-English). Beyond the numbers, it’s the first model fully compliant with the #EUAIACT transparency rules. #AI

There's literally nothing you can't compute with matrix multiplications and point-wise nonlinearities: they are Turing complete, as we've known since the 90s. There's lots of problems with LLMs, but none of them come from matrix multiplication. Why do some people keep saying that?

In the second meeting of 'Sensorimotor AI Journal Club' we covered: 📜 (B)ayesian (O)nline learning in (N)on-stationary (E)nvironments (BONE; openreview.net/forum?id=ose...) Many thanks to the first author Gerardo for an amazing presentation! 🎥 watch it here: www.youtube.com/watch?v=49PP... 🧠🤖🧠📈

Not that it comes as much of a surprise to many of us, but it's worth emphasizing once again - the 👏 brain 👏 uses 👏 distributed 👏 coding 👏. 😁 Two new papers from the #IBL looking at brain-wide activity: www.nature.com/articles/s41... www.nature.com/articles/s41... #neuroscience 🧪

Is anarchist science possible? As an experiment, we got together a large group of computational neuroscientists from around the world to work on a single project without top down direction. Read on to find out what happened. 🤖🧠🧪

🧠 #DecisionMaking isn’t confined to single hubs but distributed across the #brain, incl. #sensory, #motor & #reward areas. Data of >600,000 neurons, 279 regions, 139 mice 🐭 across 12 labs 💪 from this extraordinary study show how #cognitive processes emerge from #brainwide #dynamics. #Neuroscience 🧪

*Absolutely* beautiful work characterizing the neural transformations between imagery and perception! 🤩

We are all super happy and proud to see our work on the function and evolution of the #cephalic #furrow published in @nature.com. Let me say a few things about the background and history of this work on the #Evolution_of_Morphogenesis (1/12)
