But the most beautiful thing happened when we looked at EM volumetric data and started tracing those neurons. We found an exquisite (for vertebrate standards!) topographical organisation of the reciprocal connections that the neurons form in an enigmatic structure, the interpeduncular nucleus. The topology of the axons and dendrites was in agreement with the hypothesis of a ring attractor network-like connectivity matrix!

Here is a beautiful teasing trailer from @vilim:

Heading direction maps in the larval zebrafish? 😲
With an anatomical organisation? 🤯

Finally time for a paper tooth!
Check out the final version of our work from the Portugues lab with coauthors Hagar Lavian, You Wu, Fabian Svara and @vilim: https://doi.org/10.1038/s41593-023-01308-5

While imaging (restrained) fish larvae, we observed a peculiar bump of activity propagating clockwise and anti-clockwise over a paired hindbrain nucleus. The bump was moving when the fish was turning left or right!

Introduction! I am a biologist and neuroscientist. I got a PhD in systems #neuroscience in the Portugues lab imaging the brain of #zebrafish larvae, where described a mesmerising circuit for heading direction in the hindbrain (https://doi.org/10.1101/2022.04.27.489672).

I recently moved to the lab of Giuliano Iurilli at IIT (Rovereto, Italy) to follow up in mice my interest in subcortical circuits for naturalistic behavior.

I'm a fan of #openscience, #Python, and unconventional paradigms. Cortex is overrated!
