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

Our new paper, now published in @natcomms.nature.com , asks a simple question: when two tasks share a common structure, does the brain learn them more efficiently? Surprisingly, this was not the case. Thread below (1/7) rdcu.be/eSwvU

Dear colleagues, please check out this paper on aging and the HD system + gracefully degrading, biologically plausible HD attractor networks. Well done Matthieu!

I wrote a thing on episodic memory and systems consolidation. I hope you all enjoy it and/or find it interesting. A neural state space for episodic memories www.sciencedirect.com/science/arti... #neuroskyence #psychscisky #cognition 🧪

Foraging in conceptual spaces: hippocampal oscillatory dynamics underlying searching for concepts in memory www.biorxiv.org/content/10.1...

Thrilled to see this paper out! It's the culmination of a project begun in the depths of the pandemic with Sabrina Karjack and @zoengo.bsky.social . We continue our exploration of how children generalize when their episodic memory is not yet mature. www.nature.com/articles/s41...

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

If you're interested in the cognitive neuroscience of memory feel free to email me! I do experimental psychology, brain imaging (fMRI and MEG) and a bit of modelling. Lab is doing stuff on forgetting, aging, schemas, and event boundaries, but we're not limited to that. #psychscisky #neuroskyence

** We have up to TWO funded PhD positions available in our lab!! Apply below to find new ways to enhance memory👇 Pls retweet ** Deadline: 2nd December 1. Cross-species closed-loopTMR: tinyurl.com/bddu4tp6 2. TUS and TMR in humans: tinyurl.com/jjws5ctj Happy to chat to interested applicants.

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...

Surprise, surprise! hbr.org/2025/09/ai-g...

A while in the making, here's a short paper on how one might get from spatial to episodic memory with temporal indexing, sequence generation via grid cell analogs, + a bit of perspective/review on time, wider HPC function ... psycnet.apa.org/fulltext/202...

Dear colleagues, we have an open PhD position in computational neuroscience - spatial memory models and intracranial recordings - fully funded. Re-advertised, candidates are ideally available in the near future. A collab. with 4 labs. Apply here: tinyurl.com/yc84ctap

We did it! 🏆 We won Phase 1 and placed 2nd overall in the Algonauts 2025 Challenge. So proud of the crew @keckjanis.bsky.social,Viktor Studenyak,Daniel Schad,Aleksandr Shpilevoi. Huge thanks to @andrejbicanski.bsky.social and @doellerlab.bsky.social for support. Report: arxiv.org/abs/2507.17958

I am not an expert on EEG or CLT, but this seems to be the most expected result ever, and yet very important to show. arxiv.org/abs/2506.08872

preprint alert 🚨 1/ Can we accurately detect sequential replay in humans using Temporally Delayed Linear Modelling (#TDLM)? In our recent study, we could not find any replay and decided to dig deeper by running a hybrid simulation with surprising results. Link to preprint & details below 👇

From today, every paper submitted to Nature -if published - will be accompanied by peer reviewers comments & authors rebuttal. We started the trial in 2020; we now want to open up the review process & showcase its role in shaping & improving papers 🧪 #AcademicSky www.nature.com/articles/d41...

Congrats Volker (‪@reisnerv.bsky.social‬). Collab with Doellerlab, modeling by Viktor Studenyak via the Neural Computation Group

My colleague Dan Bush (not on BSky) at UCL is looking for a post-doc. Focus on intracranial EEG and single cell recordings from epilepsy patients + MEG recordings from healthy volunteers during spatial and episodic memory tasks. Apply here tinyurl.com/n6nkty8e

Re-posting is appreciated: We have a fully funded PhD position in CMC lab @cmc-lab.bsky.social (at @tudresden_de). You can use forms.gle/qiAv5NZ871kv... to send your application and find more information. Deadline is April 30. Find more about CMC lab: cmclab.org and email me if you have questions.

Out in PLOSCompBio: Spiking, neuro-mechanical CPG model ... dx.plos.org/10.1371/jour... No hippocampus here :-), but CPG people will hopefully enjoy this. Also, great to work with Biorob at EPFL again, and congrats to Alessandro.

Our group after a week long Strüngmann Forum in Frankfurt! Group 1 rocks!! @russellepstein.bsky.social @andrejbicanski.bsky.social @lukaskunz.bsky.social @flaviodonato82.bsky.social @ekfarran.bsky.social and others I can’t find yet on Bluesky

Postdoc alert! Come work with me on an ESRC project on the role of narratives in the learning and retention of educational material. 2 year position, start date flexible but no later than 1st September. Application deadline 1st March. #neuroskyence #psychscisky #cognition

Dear colleagues, I am advertising two fully funded PhD positions in my new group. Topics can cover grid cells, retrosplenial cortex, head direction, subiculum and boundary coding + cog maps more generally. Please direct potential candidates to the ads: www.cbs.mpg.de/stellenmarkt...
