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

More info below ⬇️
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.

One more week to apply for this cool collaborative PhD project in Bonn and Göttingen!
Are you interested in peeking inside the brain with miniscopes while mice are navigating using olfactory or visuospatial cues to find out how the hippocampus encodes this information and behaviour?
Then apply now!

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!

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!

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...

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.
