The latest story from the #QuattrocoloLab fulfills a long time dream. Are #CajalRetzius cells important for the maturation of spatial navigation? It turns out that superficial pyramidal cells in CA1 care much more about CR cells postnatal presence that deep pyramidal cells.

Please repost widely. @vanderhaeghenp2.bsky.social and I are hiring a postdoc with expertise in sensory physiology and in vivo circuit imaging/manipulation. The project centers on human-specific brain development and SYNGAP1-related disorders. Call closing soon—apply ASAP jobs.vib.be/j/119852/pos...

#QuattrocoloLab preprint out 👇! We explored changes in the proteome of hippocampal and dentate gyrus growth cones at early postnatal stages. We see that at P1 growth cones from the two subregions are very similar, but start to diverge from P3, with HP growth cones maturing earlier then DG ones.

I really had the best time visiting Vilnius University for the Summer School on Neurodevelopment! Wonderful campus, lovely city and great interactions!

And we are saying goodbye to the first postdoc of the #QuattrocoloLab. It will be sad not to have Keagan around anymore, but he is off to another great adventure! It has been a pleasure working with him and I will surely miss our gene network related discussions a lot!

The #QuattrocoloLab has 5 posters at the #FRM2025. We have interneurons, growth cones and Cajal-Retzius cells, going from proteomics to behavior. Stop by in the Development session Tuesday afternoon!

We're hiring! Our lab is looking for a postdoc to investigate the #evodevo of #cephalopod brains. Did you recently graduate, and do you want to join our EU #WEAVE project with the Simakov and @simon-sprecher.bsky.social labs? Find the application form👇Thanks for RT 🐙🦑 www.kuleuven.be/personeel/jo...

Postdoctoral researcher in evolutionary developmental neurobiology

Come join our EU cephalopod consortium to discover how octopuses and other coleoids developed their large nervous system. Postdoc position available in the Seuntjens Lab in Leuven, Belgium.

A small delegation of the #QuattrocoloLab is @corticodevelopment.bsky.social. We did a lab visit of Taormina this morning and now we are getting ready for the science. We are presenting 4 different projects here, from hippocampal growth cones to MEC development to (obviously!!) Cajal-Retzius cells!

I am looking for a postdoc with an immunology background interested in joining a Yale neuroscience lab to study how the brain controls immunity. At Yale, we have a wonderful interdisciplinary & collaborative #neuroimmune community. Please reach out or share with anyone who might be interested!

An in-house collaboration between the #QuattrocoloLab and the #NigroLab. Beautiful images and very interesting data collected.

I fell in love with neurophysiology because of the beautiful biophysical properties of stellate cells pubmed.ncbi.nlm.nih.gov/8395571/ Finally I go back to these cells and put biocytin in them and what a wonderful surprise Stained and imaged by Kristian Moan @gquattrocolo.bsky.social #neuroskyence

It was an absolute honor and pleasure to host today Ileana Hanganu-Opatz for our seminar series. Her work is super inspiring and she was the best guest! @kavlintnu.bsky.social #neuroskyence

It was a real pleasure to host Dr. Huganir @rhuganir.bsky.social today at the @kavlintnu.bsky.social for our seminar series. His work is always groundbreaking and inspirational!

I love this series of articles on @dev-journal.bsky.social! It was an honor to be interviewed for it. #QuattrocoloLab @kavlintnu.bsky.social

Transitions in development – an interview with Giulia Quattrocolo @gquattrocolo.bsky.social talks about how she became interested in neural development, how she developed her research niche during her time in the USA, and her childhood ambitions to become a volcanologist: doi.org/10.1242/dev....

So happy to share the second manuscript of the #QuattrocoloLab. This was a side project of a fantastic PhD student, Kristian Moan, that saw something cool in his data and presented it in our annual lab retreat in 2024. Now the whole story sees the light of day. 1/3

The second annual retreat of the #QuattrocoloLab is over. As usual, I was blown away by the presentations and I have so much to think about now!! So many new ideas to test! Thanks to everybody for making it so special.

Here is a flyer to print or email. Thank you very much!

We are still taking applications!

We have an open post doc position funded by an ERC Consolidator grant. It is 3 years full-time and we are looking for someone with expertise in molecular methods (engram tagging/opto/DREADDs/Immunohistochemistry) to join our big, team-science projects. www.genzellab.com/we-are-hiring

The gang is back together. Our Christmas is safe! @maxnigro.bsky.social

This is absolutely fantastic work!

Franck Polleux@franckp.bsky.social · 2y ago

Delighted to highlight our new paper in @natureportfolio.bsky.social entitled 'Synaptic basis of feature selectivity in hippocampal neurons' (thread below 👇): www.nature.com/articles/s41...

I agree with everything! I try to cultivate and promote this in the #QuattrocoloLab. And perhaps this is also why I love to study development: it has rooms for all these subfields. But sometimes it is also harder when you don’t perfectly fit in any category.

Neuroscience subfields are often siloed. Embracing an integrative approach during training can help change that, Austin Coley explains: www.thetransmitter.org/craft-and-ca...

First post on BlueSky! Biogeography of cortical #fast-spiking GABAergic neurons. We found that most fast-spiking neurons in association cortex do not express PV. Our findings challenge computational models of cortical networks based on PV counting. #neuroscience www.biorxiv.org/content/10.1...
