🧠 Next Mind Meeting Talk! Jennifer Li and Drew Robson from the RoLi Lab at @mpicybernetics.bsky.social will give a talk titled: Uncovering the neural mechanisms of spatial cognition with behavior-aware autonomous microscopes.

Thanks for the invite! Really looking forward to this

1/N: Dear colleagues, I would like to share a new paper on the subiculum, part of my PhD with the Neural Computation Group @andrejbicanski.bsky.social @mpicbs.bsky.social . We present “A theory of subicular function and generalized vector coding” that we call Disco. www.biorxiv.org/content/10.6...

For our next Mind Meeting, we will have @virginievanw.bsky.social (Paris-Saclay University, France). She will give a talk titled "Making Sense of Time (in the brain)." 🗓 April 2 | 3:00 PM 📍 In person (Zoom available)

Can whole-brain fMRI responses to naturalistic video stimuli be predicted using only transcripts? Last year, I gave a tutorial on exactly that. Since the response was very positive, I’ve now released both the tutorial notebook and the trained models publicly.

1/N: Dear cognitive map fans, I’d like to share a model I’ve been working on for a while (clearing backlog :). I show how a vector navigation architecture (VNA) and a “positional inference network” (PIN) can build Universal Cognitive Maps (UCMs) for abstract spaces. www.biorxiv.org/content/10.6...

Now out in Hippocampus. Fei Wang‘s model of Trace Vector Cells and intra-subiculum processing, consistent with know effects in CA1. onlinelibrary.wiley.com/share/CPZPYM...

Our new preprint is out on bioRxiv! @doellerlab.bsky.social We show that eye-movement sequences actively organize information by aligning with underlying structure and flexibly adapting to cognitive demands in working memory. www.biorxiv.org/content/10.6...

Reminder: This is happening tomorrow. @lukaskunz.bsky.social will be giving a talk, titled: Probing the cellular correlates of cognitive maps through human single-neuron recordings.

🧠 The Mind Meeting Series is back! Organized by us & Bicanski Lab, featuring leading scientists in cognitive and computational neuroscience. Our first speaker is @lukaskunz.bsky.social (University Hospital Bonn). 🗓 February 12 | 3:00 PM 📍 In person (Zoom available) We look forward to seeing you!

How do we achieve few-shot generalization? New work led by @fabianrenz.bsky.social dives into the role of replay in learning and using structure to generalize reward. Dream team effort with Shany Grossman @nathanieldaw.bsky.social Peter Dayan & @doellerlab.bsky.social www.biorxiv.org/content/10.6...

Our new paper, now published in Cell Reports, asks how the brain adaptively shapes its representations according to the statistical structure of the environment to overcome the limits of working memory capacity. www.cell.com/cell-reports...

New preprint: Inference over hidden contexts shapes the geometry of conceptual knowledge for flexible behaviour. In this pre-reg study, our core claim was that we don’t just learn stimulus-reward. We infer hidden context and that inference re-wires attention and neural state space on the fly. 1/8

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

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 👇
