Now published in Molecular Metabolism, improved by the helpful reviewers! We hope to continue to leverage the #zebrafish to understand the neurometabolic and hormonal regulation of appetite and beyond!

Here's a six-month time-lapse of me building the single objective light sheet fluorescence microscope at the UCSF Center for Advanced Light Microscopy!

🚨Very happy that my PhD work is now out in @nature.com!

We discovered that evolution, by acting in the midbrain, shifted the threshold to escape in Peromyscus mice, to fine-tune defensive strategies in different environments

This was a truly collaborative effort! 🧵⬇️

Thanks for everything that you did over the years. Forever grateful :)

Congratulations bro! :)

“We suggest that zebrafish phototaxis is regulated via parallel processing streams, which could be a universal implementation to change strategies depending on developmental stage, context, or internal state, making behavior flexible and goal-oriented.”

ICYMI #zebrafish folks:

Fresh from ‪@lascholz.bsky.social‬ and Conrad Lee, we offer 4 models pre-trained with diverse fps and resolutions. Leandro’s done all of the clicking. Benefit from his suffering and plug straight into automated annotation of your videos!‬

Norepinephrine changes behavioral state through astroglial purinergic signaling Both neurons and glia communicate through diffusible neuromodulators; however, how neuron-glial interactions in such neuromodulatory networks influence circuit computation and behavior is unclear. Dur...

Beautiful

microscope image of a postnatal mouse brain showing the entry point of blood vessel into the brain - fibroblasts (yellow: S100a6) form a layer at the brain's edge (meninges) and surround the blood vessel. Astrocyte endfeet (magenta, GFAP) form a layer at the brain's edge, apposed to the fibroblasts. Image also shows macrophages (cyan; CD206) and cell nuclei (DAPI, blue)

I was imaging this weekend, took this image because it was beautiful to me, the blood vessels, fibroblasts, astrocytes, & macrophages as steadfast guardians at the brain's edges. Cheers to the 'guardians' of all that is important. ❤️

Version 2 of our machine learning morphometric app is now out! Go try it on your organisms. github.com/HenHus/Husmo...

With everything that's going on, I needed this cool data 1 day before #flourescencefriday. It's my first time with #GCaMP imaging (green), and you can clearly see Aβ42 induced hyperexcitability at the same time that we also see BBB leakage (not shown)! #zebrafishrock

#sox10 and neural crest development in #zebrafish embryo—a beautiful movie from Takamiya et al.

#FluorescenceFriday is a banger collab from Hannah Moran (@chrmosimann.bsky.social) and Raeden Gray (@thelovelylab.bsky.social). SPIM image of a triple labeled zfish embryo. Sox17-green, sox10-magenta, pitx2-blue. Much more to come!!!

Here are some free/open-source sites for the preparation of scientific illustrations, including icon libraries: bioicons.com, scidraw.io, bioart.niaid.nih.gov, inkscape.org, biogdp.com, reactome.org/icon-lib

Since I'm finally moving here, here's a bit about me: my lab studies the cellular and molecular basis of vertebrate eye morphogenesis using zebrafish as a model system, combining multidimensional imaging, computational approaches, and molecular genetics. Excited to see you all!
