A hypothalamic-brainstem activity sequence underlies arousal fluctuations during daytime drowsiness https://www.biorxiv.org/content/10.64898/2026.05.26.728061v1
Curious how life adapts to extreme, rapidly changing environments?
Lukas Krone is heading to the Arctic with the Oxford Centennial Expedition to study exactly that—and is raising funds to make it happen.

Good luck, Lukas!
Following a microsleep, arousal-promoting subcortical nuclei come back online in a beautiful sequence, restoring wakefulness and responsiveness. This video captures such a recovery in a drowsy participant performing an attention task.

What happens when the brain slips into a microsleep?
An example from a highly drowsy participant showing a brief loss of responsiveness (at time 0s). Details of the research: www.biorxiv.org/content/10.6...
Learned so much @ #SLEEP2025 in Seattle. Great talks, fantastic conversations afterwards.
Thrilled to be elected Co-Chair of the Sleep Regulation & Function #GRS with @d-manasova.bsky.social
Can’t wait to shape a great program for early-career sleep scientists 🧠💤
Thanks to @nataliehauglund.bsky.social & Raquel for passing the torch! We’ll do our best to carry it forward!🔥 #SleepResearch

Great meeting #cns2025! Many thanks for organizers @cogneuronews.bsky.social. I enjoyed presenting the Data Blitz talk (www.youtube.com/watch?v=VUku...), poster, and meeting old and new friends!
Thrilled to have organized and presented at the “Coping with Sleepiness” symposium at #IOP2025 in Krakow! A fantastic experience sharing the stage with @d-manasova.bsky.social, @jtegelbeckers.bsky.social and A. Domagalik — insightful talks and great discussions! 🧠💤✨
Amazing Gordon Research Conference on Sleep Regulation and Function in Galveston, TX—fantastic people, inspiring talks, and great discussions. Also, a lot of fun beyond the science.
Our paper on CSF, BOLD, pupil, and physiological measures in sleep deprivation and recovery sleep is finally out! 🎉 Congrats Zinong! www.nature.com/articles/s41...
