The project studies how the hippocampal CA1 integrates olfactory and spatial information for goal-directed navigation. The position is a 3-year DFG-funded PhD (TV-L E13, 65%) starting April 2026, jointly supervised by Prof. Tobias Ackels at University Hospital Bonn and Dr. Oliver Barnstedt at the European Neuroscience Institute Göttingen. The project uses dual-colour miniscope calcium imaging, optogenetics, and behavioural experiments in freely moving mice. Application deadline is 31 January 2026, with applications sent by email.
PhD position in systems neuroscience!
Excited to start a new DFG-funded project together with @obarnstedt.bsky.social to study olfactory–spatial coding in CA1.
🔬 Dual-colour miniscope Ca2+ imaging
🐭 Freely moving behaviour & optogenetics
⏳ Start: April 2026 | Deadline: 31.01.2026

What if the DNA methylation enzyme DNMT1 isn’t just about DNA?
Our new preprint reveals a cytosolic role for DNMT1 as a scaffold controlling neuronal morphology via DOCK7–Rac1/STMN1 signaling & mitochondrial trafficking.
A paradigm shift in DNMT1 biology! www.biorxiv.org/content/10.1...

Excited to see this out (now in print).
A fantastic collaboration by former student Rudolf Degen and current PhD student Victoria Switacz, who did an amazing job closing the deal on this one.
Give it a read if you like, but beware - it's nerdy ephys at its best.
Olfactory neuroscientists have known for a while that their stimuli stink. A new analysis illuminates the extent of the problem.

2024 marked the 10-year anniversary of the FENS-Kavli Network of Excellence. We warmly invite you to explore the 10-Year Report, showcasing its impact on science, mentoring, outreach, advocacy, and personal achievements. @fens.org @kavlifoundation.bsky.social fenskavlinetwork.org/fkne-10-year...
With the huge challenges facing scientists, I call on peer reviewers to reflect on their role as gatekeepers to trainee career development and scientific progress. You can maintain high standards for rigor while being kind and not demanding an extra year of studies for every paper revision.
...and well deserved.
Congrats!!!
I am deeply grateful for this award, which not only recognizes my work but also reflects the invaluable contributions of my team, mentors, and supporters!
It inspires me to continue working with my lab to deepen our understanding of how we perceive and interpret our environment.
⏰ Last chance! Today is the final day to submit your #AChemS2025 abstract!

We are looking for two PhD students interested in the regulation of habit formation. Habits are useful to decrease cognitive load, but carry the risk of becoming stereotyped and hard to control - it’s hard to shake a bad habit. The fruit fly Drosophila also forms habits and we […]

There's a movement in neuroscience suggesting we should be pursuing bigger bets with larger teams. I think there's a case for doing a bit of this, but I think it's a bad idea to prioritise it for two reasons, and a good case for saying we should be moving in the exact opposite direction. 🧠🧪
