We have now published a new and massively extended/reworked preprint of the whole-body larval with over 50 figures

https://www.biorxiv.org/content/10.1101/2024.03.17.585258v1

All the analyses, plots and figures should be reproducible in with the code provided:

🚨 New is online! 🚨

"Many weak and few strong links" seems to be a common pattern in many . We show that this skewness in interaction strengths can enable stabilising effects of network structure. It should hence receive more attention in and , especially in studies based on random matrices!

(Btw, just in case you are looking for guest speakers, I highly recommend the first author, Franziska Koch! 😉)

How interesting. In , the brain – the pattern of synaptic connections among neurons – is also organized with many weak and few strong links.

Little known facts of the :

The original connectome was mapped from 5 different volumes, from 4 hermaphrodites and 1 male.

White et al. 1986 https://royalsocietypublishing.org/doi/10.1098/rstb.1986.0056

Brenner, without skipping a beat, stated this served his purposes just fine: to study variability in synaptic connectivity among otherwise isogenic animals – and found lots, enough to state that genetic determinism w.r.t. neural circuit configuration as understood at the time was largely hogwash.

Want to bring a whole country up to the task of mapping the synaptic diagram of not one but many mouse brains, at a reasonable cost? Within about a decade? Here is an approach to get there: https://albert.rierol.net/tell/20230823_connectomics_research_base.html

Really excited to share the lab's first Drosophila paper and it's a big one. Check out our preprint https://shorturl.at/gqrvO where we present the complete neural connectome of an animal circadian clock . 🧵 (1/8)

Mubarak Syed kicking off the grounding us in the land and the history and the rich diversity of the Pueblo of Sandia. https://www.pueblobrainscience.org absolutely tremendous outreach efforts bringing in and supporting tomorrow’s scientists.

schoppik,

Jim Truman leads with of the mushroom body (a locus of memory). He's walking us through a most beautiful piece of work. Special shout-out to the foresight it took to begin this work before there was a available so as to inform ongoing work.

tl;dr the molecular events that shape larval development can fade, allowing trans-differentiation of neurons (a shift from one brain area to another).

The FlyEM MANC is now available on NeuronBridge.janelia.org. researchers can use this tool to match the MANC electron (EM) data against light microscopy (LM) data, like that from the Janelia FlyLight project. A user can interactively examine matches right in the browser by clicking the "View in 3D" button. Interactive views are sharable, too... (1/3)

Open science project OpenWorm simulates the roundworm Caenorhabditis elegans at the cellular level.
A deep, principled understanding of the biology of this organism remains elusive.
The long-term goal is to model all 959 cells of C. elegans. This bottom up simulation is pursued by the OpenWorm community.

Check out our new work on weighted neural models! 🧠🤖

Recently, we’ve seen tons of work using generative models to elucidate candidate principles of neural connectivity.

We envision this will help us understand development and also impact structural learning in ANNs in the future! 📚🧑‍🏫

Today the peer-reviewed version of our preprint is out:

"The of an insect brain"
https://www.science.org/doi/10.1126/science.add9330

Congrats to co-first authors Michael Winding and Benjamin Pedigo, and to all our lab members and collaborators who made this work possible over the years. A journey that started over 10 years ago–and yet this is but a new beginning. So much more to come.

See my on the preprint from back in the Autumn: https://mathstodon.xyz/@albertcardona/109422190525090990
