Tiny brain, but well behaved. Likes to socialize and loves underwater singing. Advocate for transparency. Surfacing Danionella papers for you.

Our lab's latest paper on the neurobiology of collective behavior is now published www.nature.com/articles/s41... This is the work of a great team in the lab - led by Jo-Hsien Yu, with Geoff Meyerhof, Jimjohn Milan, and Julia Napoli @nature.com @danionella.bsky.social

The first Danionella paper from the lab. Danionella cerebrum is transparent, so you can see all of the internal organs. But what sensory information are the organs sending to the brain? In our new preprint, Emily Bayer wanted to find out. 1/4 www.biorxiv.org/content/10.6...

Our collaborative paper with Palka Puri and Johnatan Aljadeff is now published in @physrevlett.aps.org. We find that Danionella fish move in schools by copying a neighbor's heading direction @danionella.bsky.social aljadeff.ucsd.edu journals.aps.org/prl/abstract...

Collective Motion in Danionella Emerges from Discrete Copying Interactions
Understanding how animals move as collectives requires knowledge of movement and interaction rules implemented by individuals within such groups. We report that micro glassfish Danionella cerebrum exh...

I thought I was a quirky little underdog fish with cool tricks, widening the model-organism spectrum. Suddenly, headlines: "Billion Dollar Fish Takes Over" Holy Mackerel! I guess there weren't any smaller fish to fry. Anyway, I'm still the same, still making the case for model diversity.

Tiny, transparent, and now charted! Our brain atlas of adult Danionella cerebrum includes >200 annotated regions, 29 whole-brain in situs, and male/female reference volumes – openly available, versioned and extendable. Work by @nkadobyansky.bsky.social and team. www.biorxiv.org/content/10.6...

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...

Beautiful work led by Yansong (Kevin) Lu on skeletal muscle growth in zebrafish, giant danio, Danionella cerebrum, and killifish. HCR, new image analysis tool, scRNA-seq, and CRISPR. New international collaborations between Uni Melbourne, NCVC/Osaka, Stanford & ARMI www.biorxiv.org/content/10.6...
New morphometric analysis tool developed by Lu et al. applied to skeletal muscle cross-sections of four different juvenile teleost fish species. Main finding: Mosaic hyperplasia, i.e., the addition of new myofibers in the deep myotome, is near-zero in the small Danionella but dramatically enhanced in the giant danio relative to the intermediate grower zebrafish, establishing this mode of hyperplasia as a main driver of skeletal muscle growth in differently sized fishes.

For today's #fluorescenceFriday, a transgenic Danionella cerebrum, the world's (second) smallest vertebrate (yep, "stout infantfish" are smaller, but no one has made them glow yet!). Picci by our very own @xinwei-wang.bsky.social

Switched waters to Bluesky. Still singing, still transparent, and back to having the smallest vertebrate brain around.
