Congrats Laurent, so well-deserved! Thrilled to be working with you in the near future!

Our conclusion: there is a signature of IH in sleep but the causes might be found in wake!

Thanks @institutducerveau.bsky.social, @inserm.fr, @aphp.bsky.social and @erc.europa.eu for supporting this work!

Can you learn while sleeping? Does sleep help you solve problems? What is the effect of sleep on brain metabolism?

Sleep is not a homogenous state - just like wake. Asking the role of sleep is as fair as asking the role of wake!

The cover is for a Perspective piece by Lüthi & Nedergaard who discuss microarousals, and propose an inverted U-shaped relationship to reconcile their essential and disruptive roles: www.cell.com/neuron/fullt...

What a pleasure to be interviewed by science writer @davidarobson.bsky.social, what an even greater pleasure to read his visionary narrative in BBC future!

Agree! Watch out for a first Perspective on this proposed by Maiken and me, coming out on Monday, Jan 13, in Neuron.

Important study on the timing pattern of #sleep #spindles in human EEG and of fingerprints that characterize individuals across age and demographic factors 👏👏

Merci Thoma!

Amazing work from the team of Anita Lüthi!

Une nouvelle horloge pour structurer le sommeil Des scientifiques au sein de la FBM-UNIL ont identifié un nouveau rôle du locus cœruleus dans le sommeil et ses troubles. Cette région cérébrale permet la transition entre les états du sommeil et le m...

Alors c’est parti: 1er post, en français:

Récente découverte @unil.bsky.social: une toute petite région du cerveau qui s’appelle « locus coeruleus » détermine si nos nuits sont bien rhythmées entre les phases du #sommeil paradoxal et profond.

🔵 blue spot alert: Anita Luethi's team reports a dual role of #locuscoeruleus in #sleep in Nature Neuroscience @natureportfolio.bsky.social

1) high LC activity facilitates cortical microarousals
2) low LC activity is required for NREMS-to-REMS transitions
