New preprint out 🎉

What happens to the hippocampal “place code” when an animal is actively engaged in a task?

The answer surprised us (and might surprise you too!).

Let's dive in ⬇️

"Hippocampal trace coding dominates and disrupts place coding" www.biorxiv.org/content/10.6...

🚀 New preprint from the lab! Our first foray into the subiculum uses in vivo whole-cell recordings to show that dendritic plateaus are a prominent, learning-dependent signaling mode of subicular neurons. Feedback is welcome!

2025: A Review of the Year in Neuroscience Enlightening the brain

Just published my review of neuroscience in 2025, on The Spike.

The 10th of these, would you believe?

This year we have foundation models, breakthroughs in using light to understand the brain, a gene therapy, and more

Enjoy!

Very cool, congrats Yangfan!

🥳Excited to share our latest human multipatch paper, now out in @natneuro.nature.com
🧠 We studied the cellular and synaptic physiology of human L2–3 pyramidal neurons and identified subtype-specific local connectivity rules across individuals.

One more week left to apply for this 4-year full-time TECHNICAL ASSISTANT position at the EUROPEAN NEUROSCIENCE INSTITUTE GÖTTINGEN!

Congrats to lead authors @alexattinger.bsky.social and Tony Drinnenberg and all our amazing collaborators! Check out the thread below for new work from the lab on plasticity, cortex and spatial representations for navigation!

Cross-species implementation of an innate courtship behavior by manipulation of the sex-determinant gene In accepting a courting male, Drosophila subobscura females require nuptial gift giving in which a male gives regurgitated crop contents to her mouth to mouth. No similar behavior is found in D. melan...

doi.org/10.1126/scie...

This seems rad: overexpressing FruM in a set of proboscis-motorneuron-projecting neurons makes melanogaster males add food-sharing to their courtship repertoire.

It is fascinating to see evolutionary shifts in behavior be tied so concretely to shifts in brain development!

The connectome of the entire male Drosophila central nervous system is out!! Acquired using FIB-SEM @ 8x8x8nm, we aligned 7.5 mio 2D images aligned into one seamless 3D volume, which was used to segment & proofread neurons and synapses. @hhmijanelia.bsky.social

Our lab at the European Neuroscience Institute in Göttingen is looking for a highly skilled and motivated TECHNICAL ASSISTANT. Are you proficient in histological and wet lab techniques and lab management? Then come apply for our position (4 years contract)! umg.recruiting-portal.com/r/z004xflh7r...

Happy to share that I just started a W2 professorship at the University of Bremen! Yay tenure! While I already start teaching now, the lab will stay in Freiburg until May while we get things ready. Super excited about this new chapter! We’re also hiring! Please get in touch if you’re interested!

I’m pleased to share our new paper, “Hippocampal ripple diversity organizes neuronal reactivation dynamics in the offline brain”, out in @cp-neuron.bsky.social !

With @vitorlds.bsky.social and David Dupret, we show that diversity in ripple current profiles shapes reactivation dynamics

Thanks to the @linmagdeburg.bsky.social and its great research community for all the fantastic support along my scientific journey! Looking forward to the conference www.lin-magdeburg.de/institut/lea... in 24 days!

Do we understand how neural networks work? Yes and no.

There is some confusion about whether or not we understand LLMs. The answer is yes and no, but mostly no. It's a complicated enough question that it seemed like it needed an article.
