Excited to see this preprint out! Siyuan Mei did exceptional work leading this project, and it was a great experience working with the Herz lab. How do zebrafish update their internal compass? They use a multi ring shifter network, similar to flies despite 550M years of divergence. Full thread ⬇️
Very excited to share this thread on our recent paper! We show how Zebrafish integrate visual navigation signals in aligned topographic maps. Full thread below🧵
1/n: A new collaborative preprint from the lab to start the year: "A multi-ring shifter network computes head direction in zebrafish" together with Siyuan Mei, Martin Stemmler and Andreas Herz from the LMU, Munich.
Have you ever wondered how the brain should represent the sensory world in order to generate behavior? Read our new preprint: work by Shuhong Huang shuhonghuang.bsky.social with our long-standing collaborator James Fitzgerald at Northwestern.

New paper alert! 🚨
We found that the brain's compass is remarkably stable at two scales
1️⃣ the system maintains its internal organization for weeks
2️⃣ It "remembers" its orientation for weeks, even after a single visit
This may be key to how the brain aligns its other maps.

One of the world's leading brain research centers is shifting away from fruit flies and toward a tiny, transparent fish. The goal: to understand how brains control the behavior of an animal or human. n.pr/4vV8dYM

Excited to share my postdoc work from
@schierlab.bsky.social and Rainer Friedrich! 🐟👃
How does the brain decide whether an odor is good or bad? In larval zebrafish, we find that odor preference is reflected in spatially cohesive neuronal domains of the olfactory bulb. 🧵
Very proud to see our paper selected as one of Nature’s 2025 highlights!

First whole-brain recording of social sound processing in a vertebrate. Surprises start in the hindbrain; thalamus gates conspecific calls; male and female brains diverge downstream. Work by @joerghenninger.bsky.social, @mh123.bsky.social sky.social and team. www.biorxiv.org/content/10.6...
