Post-translational Tuning of Human Cortical Progenitor Neuronal Output

The striking expansion of the human neocortex is driven by the ability of radial glial cells (RGCs) to prolong neurogenesis without exhausting their progenitor pool, thereby producing more neurons, pa...

I am very happy (and a bit scared) to present to you what we have been working on over the last 4 years. This manuscript is exactly what I dreamt of when I started the lab and I could not be happier and prouder of the outcome!

We are #hiring! Interested in comparative neuroscience? Check details here (www.unifr.ch/bio/en/depar...). We look for a motivated #PhD student or #PostDoc to combine genetics, physiology, neural circuit tracing, and behaviour to study taste processing evolution in #Drosophila. Please repost.

Proud to share my main postdoc work! 🧠 I asked: How to build a #brain that lead to #individuality? We show that adult brain wiring isn't fully predictable from genes or environment alone— the #stochastic nature of #development is a key third factor. #NatureNeuroscience www.nature.com/articles/s41...
