Neocortical long-range inhibition promotes cortical synchrony and sleep
Nature, Published online: 09 September 2026; doi:10.1038/s41586-026-10876-y In mice, a sparse population of sleep-active long-range inhibitory neurons in the neocortex promote widespread cortical synchronization and sleep, revealing a cortical mechanism that contributes to the regulation of sleep.

Another postdoc piece out today in @natneuro.nature.com! 🧠💤 In unimpaired older adults, frontal tau pathology tracked with lonely NREM slow waves that fail to travel — and these waves predicted worse overnight memory. full-text: rdcu.be/jDcgH2sK8VZa @ucberkeleyofficial.bsky.social 🧵👇

(5/6) What happens if you silence LC synapses? Using an optoGPCR (PdCO), we found that shutting down LC→PRN boosts sigma power and deepens NREM sleep. Silencing both PRN + BF was even more effective.

Yuval Nir @labnir.bsky.social · 10/09/2025
(4/6) Timing is everything ⏱️ Optogenetic activation showed that sound-evoked awakening depends on which LC neurons are active AND when they fire - synchrony with the sound is key.

Yuval Nir @labnir.bsky.social · 10/09/2025
(3/6) Here’s the twist: only the LC→PRN pathway shows a fast NE surge when sounds are played during sleep. That rapid signal predicts whether the sound will wake the mouse.
