Amid the rise of billion-parameter models, I argue that toy models, with just a few neurons, remain essential—and may be all neuroscience needs, writes @marcusghosh.bsky.social. #neuroskyence www.thetransmitter.org/theoretical-...

We’re very happy to share that our work on 3D spatial memory was published in PNAS just before the end of the year! 🎉 Link: www.pnas.org/doi/10.1073/... (1/8)

Congratulations @maxhinrichs.bsky.social on winning the Best Presentation Award last week at the MPUTC Symposium: Frontiers in Neuroscience & Technology - Emerging Minds.

New preprint! Have you ever wondered, what are these fuzzy simplicial sets, the theoretical framework behind e.g. UMAP? Here we show that you may simply see them as marginal distributions over simplicial sets. This provides a generative model for UMAP. (1/2) arxiv.org/abs/2512.03899

Interesting findings with important applications

✨My first first-author paper is out✨ Entorhinal grid-like codes for visual space during memory formation in @natcomms.nature.com ➡️ rdcu.be/eLRm2 Big thanks to everyone ‪@isabellacwagner.bsky.social‬, @tobiasstaudigl.bsky.social, @olejensen.bsky.social, @doellerlab.bsky.social, @clauslamm.bsky.social

⏳ Deadline approaching! Apply by 13 Oct for the Postdoc in Cognitive Neuroscience at MPI Leipzig.

New preprint from the lab and great work by Fei Wang. We show how subiculum trace vector cells can be modeled consistent with known effects in CA1. Traces are driven by a mismatch learning rule to keep associative memories in line with experience. www.biorxiv.org/content/10.1...

Join us at the Max Planck Institute in Leipzig as a Postdoc to explore cognitive maps in the human brain: learning, memory & the formation of structural representations. Excellent infrastructure with a leading scientific network. Apply by 13 October: postdocprogram.mpg.de/node/21187

🚨 New preprint! Impact of Task Similarity and Training Regimes on Cognitive Transfer and Interference 🧠 We compare humans and neural networks in a learning task, showing how training regime and task similarity interact to drive transfer or interference. www.biorxiv.org/content/10.1...

Congratulations to @reznikdan.bsky.social and @sofievalk.bsky.social for this tremendous achievement!

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...

Excellent outcome of #Algonauts2025 challenge by @algonautsproject.bsky.social: Phase 1 winners, 2nd overall. Congratulations to everyone involved.

Excited to share that our work on the interplay of symmetric learning rules and successor representations (SR) is published in @plos.org (comp.bio) Work done together with @doellerlab.bsky.social, @caswell.bsky.social and Juergen Jost. doi.org/10.1371/jour... #neuroskyence #compneurosky 1/n

🚨Preprint Alert: Who Does What in Deep Learning? Multidimensional Contribution of Neural Units using Game Theory: arxiv.org/abs/2506.19732 The result of my MSc thesis is out with @kayson.bsky.social @fatemehhadaeghi.bsky.social @patrickmineault.bsky.social @kordinglab.bsky.social, Claus C. Hilgetag

📣 Very excited for our symposium on “Building Knowledge Structures” tomorrow at 16:30 at @pug2025.bsky.social Together with amazing people: @barnaveliirina.bsky.social @lukaskunz.bsky.social @mirkothm.bsky.social and Andrea Greve

New preprint! We explored how learned movement patterns affect our sense of traveled distance and proposed a neurocomputational model that leverages embodied memories to denoise spatial codes. 🔗 www.biorxiv.org/cgi/content/...

Our paper in @natcomms.nature.com, we show how cognitive maps in the hippocampal system could solve the general problem of representing and relating multiple alternative action plans.  doi.org/10.1038/s414... With @doellerlab.bsky.social, Patrick Haggard, @vigano.bsky.social, Daniel Reznik

🧠✨How do we rebuild our memories? In our new study, we show that hippocampal ripples kickstart a coordinated expansion of cortical activity that helps reconstruct past experiences. We recorded iEEG from patients during memory retrieval... and found something really cool 👇(thread)

Come meet our lab at #CNS2025 today during the Poster Sessions! 🧠 We’re excited to share work on mental organization, knowledge representation, conceptual spaces & task simulation. Details are in the thread 👇
