New preprint from the lab! A frontal motor circuit for economic decisions and actions: www.biorxiv.org/content/10.6... We use a novel task in mice, cortex-wide imaging and optogenetics, NPX recording and modelling to reveal a circuit mechanism that transforms abstract decisions to spatial actions.

Please share! 🧠 Opportunity for a PhD position: Studying interneurons and memory, using cutting-edge techniques, such as patch-clamp electrophysiology, in vivo calcium imaging, optogenetics and behavioral experiments. Interested? Have a look here for more information: www.fens.org/careers/job-...

Now that the science days are over, I can happily share some of my designs :) Thanks to all the @in-code.bsky.social members who made these days a success! It was intense but worth it! And huge thanks to @sophiekb.bsky.social that was in charge of making this happen

🚨New paper alert! We studied the long-term consequences of SSRI use during pregnancy on the offspring in rats in a seminatural environment. We found that perinatal FLX exposure significantly increases sexual behavior in adult male rats. @uitnorgesarktiske.bsky.social #neuroscience #neuroskyence

And for me the big question is: What about representational drift? 😄 Manifolds can be mapped, but individual neuronal responses change. That’s neat, but how does it make sense? How can perception stay stable if the neurons keep changing? I’m sure manifolds will help us understand that too… 🧠🧪 3/3

🚨 New Article Alert! 🚨 Our latest research reveals how long-term consumption of a cafeteria (CAF) diet impacts the ventral tegmental area in rats. 🍔🍟🍩#Neuroskyence @uitnorgesarktiske.bsky.social www.sciencedirect.com/science/arti...

A non-value-based system in the brain automates decision-making and frees up cognitive resources for other tasks, a new study in mice suggests. By Holly Barker #neuroskyence www.thetransmitter.org/neurobiology...

A new paper from the group is online: we show that longterm low-frequency stimulation alleviates seizures beyond stimulation periods and reverses epilepsy-associated synaptic alterations. #TrEPILab www.sciencedirect.com/science/arti...

Check our new manuscript on ‚Coordinated representational drift supports stable place coding in the hippocampal CA1’ by Ole Sylte, Antje Kilias, Marlene Bartos and Jonas Sauer. www.biorxiv.org/content/10.1...

New paper out! We found functional neuron classes in the mPFC with different spatial tuning properties (generalised vs. trajectory-specific) and distinct contribution to the encoding of task space. Great job by the first author Hannah! www.cell.com/cell-reports...

New from the lab!! 👉🏼 authors.elsevier.com/a/1kgT43BtfH... 📝 @cellpress.bsky.social We discovered that genetically-defined neuron types in the hippocampus form unique manifolds! Dual color imaging, chemogenetics and topological analysis all at once! With Juan Gallego @juangallego.bsky.social

Slow life as a scientist

First preprint from our lab! An @jerlich.bsky.social collaboration We developed novel frameworks to study multi-agent decisions in mice. Mice flexibly shift their decision preference under social competition, by integrating real-time self and opponent information! www.biorxiv.org/content/10.1...

Don't miss the chance to present at the world's northernmost university city while catching the midnight sun 👇

Stable maps from drifting neurons: CA1 solves the "representational drift paradox" through coordinated population dynamics. New preprint w/ @antjekilias.bsky.social , Marlene Bartos and @jf-sauer.bsky.social showing that representational drift isn’t random—it’s structured to preserve information🧵👇

New paper alert! We studied the temporal copulatory patterns of female rat sexual behavior and proposed a new behavioral assessment method. #behavioralneuroscience #UiTtheArcticUniversityofNorway #neuroscience www.sciencedirect.com/science/arti...

Our new preprint on long-term low-frequency stimulation in MTLE is online. We show that LFS has lasting effects on seizures even during stimulation-free periods and induces ultrastructural changes at the PP synapse.

If you're into behavioral neuroscience and/or machine learning and looking for a postdoc, check this out - excellent lab and mentor! 👇

Having spent 4+ years in @jf-sauer.bsky.social lab - this is a fantastic opportunity! Great mentor & super exciting work on neural population code!

A bit late to the Bluesky party but here’s our work showing a coordinate system for behavioural space, and an algorithm for computing behavioural sequences in the mFC: www.nature.com/articles/s41...
