Congratulations Max for a successful defense!🎉📓 In his master's thesis under the supervision of our postdoc @danielhummel.bsky.social, Max Widmann explored how the neural activity of motion integration circuits in the anterior hindbrain changes during the first days of larval development. 🐟🧠

Congratulations to @ashritocyte.bsky.social on an amazing PhD defense! 🎓🐟 Ashrit uncovered structure in zebrafish behavioral variability, showing how past decisions influence what fish do next. He also shaped lab life, from cooking and game nights to chats and teaching. We wish him the best of luck!

The animal is the same. The stimulus is identical. Yet the behaviour varies. Why? In our new study, @ashritocyte.bsky.social explores the sources of this behavioural variability under fully controlled conditions in larval zebrafish doing optomotor response. (1/7) www.biorxiv.org/content/10.6...

🚨New preprint doi.org/10.64898/2026.06.07.730682. We show that zebrafish larvae exhibit complex, internally generated, spontaneous behavioral patterns in the absence of stimuli. These dynamics can be described by a simple Markov process with transition probabilities that change over time.

We are excited to share our collaboration with @pheereynolds.bsky.social, Robert Hindges & team on retinal plasticity, now out in Neuron! This work shows how visual experience during early development changes the anatomical and functional properties of amacrine cells and ultimately behavior!

New paper out: www.cell.com/iscience/ful... Congratulations to our former PhD student @maxcapelle.bsky.social whose work reveals that the switch in light preference across zebrafish development is driven by a reweighting of three parallel visual processing pathways.

How do brains make decisions when faced with multiple, potentially conflicting cues? In our latest preprint, we show how #zebrafish use an additive strategy and process multiple visual features through anatomically distinct parallel pathways tinyurl.com/mvkn8em9 Thread 👇

Meet Max, a life science master's student at @uni-konstanz.de who joined our lab last year to work on ablating luminance change detecting cells in the larval zebrafish brain using 2P microscopy. His excellent work contributed to efforts in the lab to probe neural circuits underlying decision-making.
