About 140 years ago Edinger and Westphal described a small brainstem nucleus involved in the pupillary light reflex. Thomas TOPILKO et al Nicolas Renier discovered using 3D imaging/ClearMap & more, that this nucleus also controls nesting behavior in mice 🪆🐭disq.us/t/44x9wl2

Large-scale use of large-scale in titles. (an otherwise excellent set of papers!)

Not hungry? Your friendly gut bacteria might tell you so. It was great to collaborate with Ilana Gabanyi from Institut Pasteur, since 1887 (an old friend from Rockefeller University) on this story! science.org/doi/10.1126/sc…

A brilliant study from Thomas TOPILKO and colleagues from the Nicolas Renier group demonstrates that preparatory nest building in pregnant females relies on the activity of peptidergic neurons in the Edinger-Westphal nucleus. Here is our take (w Marcelo Dietrich 马塞洛)…sciencedirect.com/science/articl…

Last week to register!!! You are a PhD student or postdoc interested in neurodevelopment, do not miss this fantastic opportunity !! Do not wait!! cajal-training.org/on-site/neuro-…

Peptidergic neurons in the Edinger Westphal nucleus of pregnant mice enable maternal preparatory nesting before pups are born. Read Onur Iyilikci & Marcelo Dietrich 马塞洛's preview of this work: bit.ly/3svcUKH And find the original study here bit.ly/3kCzWus

This is going to be so useful for our investigations of NeuroVascular plasticity in this region!

Very proud of Alba Vieites Prado , former postdoc of my lab, setting up her lab at CiMUS !

This was one of the best meeting I ever attended to. Amazing speakers and still floored by all the work on « unconventional » animal models!

I had so much fun hosting Hiroki R. Ueda at the Institut du Cerveau - Paris Brain Institute with Alain Chédotal. Hiro is pushing ever further our understanding of sleep, while creating revolutionary methods! (Have you heard of CUBIC?😉)
