Excited to share the latest work from the lab: rdcu.be/eRWuD Great team effort, led by @enriberti.bsky.social first at @unil.bsky.social and now @unifr.bsky.social; with fantastic collaborators @ribeirocarlitos.bsky.social and @dahaniel.muench.bio.

🧠🌟🐭 Excited to share some of my postdoc work on the evolution of dexterity! We compared deer mice evolved in forest vs prairie habitats. We found that forest mice have: (1) more corticospinal neurons (CSNs) (2) better hand dexterity (3) more dexterous climbing, which is linked to CSN number🧵

First neurons didn’t appear overnight. We trace their roots to ancient secretory cells - showing how lifestyle & behavior shaped the evolution of first synapses.🧠🌊 #Evolution #Neuroscience Our latest in @natrevneuro.nature.com Link: rdcu.be/eMX3E @jeffcolgren.bsky.social @msarscentre.bsky.social

By comparing differently tuned glomeruli, this work shows that the brain uses different circuit layouts for specialised vs general smells, offering new insight into how odour meaning is encoded. buff.ly/XDmo4Ue

Excited to announce our new pre-print (www.biorxiv.org/cgi/content/...)! This collaborative work (co-led by Adriane Otopalik and Gerry Rubin) examines how neuronal circuits regulate social behaviors, like courtship🫶 and aggression🥊, across sexes. #neuroscience #Drosophila #WomenInSTEM 🧪1/

Excited to share our new #biorxivpreprint We discovered that the fruit fly #drosophila erecta requires food odor to mate and arousal is further enhanced by social group motion. Cross-species analysis of brain activity reveals a novel gate evolved from within a conserved circuit shorturl.at/gGYm7

Excited to share our new #biorxivpreprint: “Sexual dimorphism in the complete connectome of the Drosophila male central nervous system” www.biorxiv.org/content/10.1... We describe the #connectomics reconstruction and analysis of an entire adult #maleCNS #drosophila central nervous system. 1/10

Having personally sworn for years that insects don’t use GPCRs for odour detection, Suguru Takagi (@sugurutakagi.bsky.social) discovers that, in fact, they sometimes do … www.biorxiv.org/content/10.1...

Exciting news for #drosophila #connectomics and #neuroscience enthusiasts: the Drosophila male central nervous system connectome is now live for exploration. Find out more at the landing page hosted by our Janelia FlyEM collaborators www.janelia.org/project-team....

🚨Preprint🚨 What started as an attempt to compare CT scans of diverse fly brains, ended up a new concept for analysis & segmentation of difficult tomographic data. No ground truths, no training, just maths. This is TopoTome, topological data analysis of 3D images www.biorxiv.org/content/10.1...

The final version of our paper on how ants and possibly other insects use a crazy mechanism involving extensive transcriptional interference to regulate odorant receptor expression is now open access in my favorite journal, @currentbiology.bsky.social authors.elsevier.com/sd/article/S...

A new study in ants from @danielkronauer.bsky.social reveals a previously unknown mechanism that ensures that each olfactory neuron expresses only one odorant receptor, with broad implications for the study of gene regulation. #RockefellerScience https://bit.ly/4pwPFLY

You just finished your PhD and you are looking for a postdoc to study stress-dependent modulation of learning. We are using the powerful fly model to understand the underlying circuits and mechanisms. You can apply here: emploi.cnrs.fr/Offres/CDD/U...

Neuronal diversity is written in transcriptional codes 🧬. But what is the logic of these codes that define cell types and wiring patterns? To find out we built a #scRNAseq developmental atlas of the Drosophila nerve cord and linked it to the #connectome 🪰🧠 #preprint thread ⬇️1/8

Some behaviors are genetic, not learned, which means, theoretically, that they are transferable. That is exactly what this experiment demonstrated. Manipulation of one gene made one species of fruit fly gain the behavior of another. 🧪 Link: www.science.org/doi/10.1126/...

Thank you @thetransmitter.bsky.social and @martajhill.bsky.social for highlighting our work!

Exciting new paper from the Bahl lab @bahllab.bsky.social @zwitscherarmin.bsky.social and Katja Slangewal about parallel and convergent processing pathways of different visual features in the larval zebrafish brain🐟 www.biorxiv.org/content/10.1...

Some parts of the Drosophila olfactory circuit have evolved more than others, according to a new comparison of two fruit fly species’ connectomes. By @martajhill.bsky.social #neuroskyence www.thetransmitter.org/connectome/c...

With @megyounger.bsky.social's lab, et al., we present the first connectomics work in the disease-vector mosquito Aedes aegypti, revealing how its brain is wired to detect host cues. Preprint: doi.org/10.1101/2025... #Neuroscience #Connectomics #vEM #VectorBiology 🧪

New preprint from @darbly.bsky.social‬ @briandepasquale.bsky.social‬ and my labs! If you love (or hate) mosquitoes, have a look: doi.org/10.1101/2025... We used TEM to describe the circuitry used for CO2 detection by mosquitoes. As usual with mosquitoes, nothing is as expected! 🌬️🦟

🚨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 www.nature.com/articles/s41... This was a truly collaborative effort! 🧵⬇️

Finally it's out! www.nature.com/articles/s41... How flexible are essential innate behaviours and their underlying neural circuits? @felixbaier.bsky.social & I, with Hopi Hoekstra and @farrowlab.bsky.social, addressed this by studying the #evolution of threat avoidance in Peromyscus mice.
