Why do some worms graze on bacteria while others hunt and kill? Our study, published today in Nature, reveals how predatory aggression evolved in nematodes. Led by @gunizgozeeren.bsky.social and @leoboeger.bsky.social across the @jameslightfoot.bsky.social and @monikakscholz.bsky.social labs.

Predatory aggression evolved through adaptations to noradrenergic circuits - Nature

Noradrenergic circuits support and balance aggressive behavioural states in predatory nematodes, distinguish predatory from non-predatory nematode species and are associated with the evolution of comp...

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.

Thanks Misha for the shout-out! It has been a truly mind-opening journey. WHOLISTIC is one step towards whole-organism neuroscience and a true physiological observatory - with extensions on the way! I am continually amazed by what the data reveals - so much remains to be discovered and mined.

Misha Ahrens@mishaahrens.bsky.social · 11mo ago

Preprint - Excited to present WHOLISTIC, which extends the concept of whole-brain functional imaging to the entire body. Pioneering work by incredibly talented Virginia Ruetten @vmsruetten.bsky.social, this platform reveals whole-organism cellular dynamics in vivo. www.biorxiv.org/content/10.1...

It was a good experience to step back and briefly take stock of the amazing progress in connectomics since I started working on this stuff (20 years ago!) thanks as well to @natrevneuro.nature.com for the constructive editorial interactions.

New preprint from @darbly.bsky.social‬ @briandepasquale.bsky.social‬ and my labs! If you love (or hate) mosquitoes, have a look: doi.org/10.1101/2025... We used TEM to describe the circuitry used for CO2 detection by mosquitoes. As usual with mosquitoes, nothing is as expected! 🌬️🦟

Recurrent connectivity supports carbon dioxide sensitivity in Aedes aegypti mosquitoes

The mosquito Aedes aegypti′s human host-seeking behavior depends on the integration of multiple sensory cues. One of these cues, carbon dioxide (CO2), gates odorant and heat pathways and activates hos...
