1675-Neocortical Long-Range Inhibition Promotes Sleep
This paper investigate the neocortical mechanisms that regulate sleep and arousal, specifically focusing on a sparse population of somatostatin and chondrolectin-expressing (Sst-Chodl) inhibitory neurons. Utilizing intersectional genetics and two-photon calcium imaging, researchers demonstrate that these long-range projecting neurons are preferentially active during low-arousal states such as slow-wave sleep and quiet wakefulness. Furthermore, experimental optogenetic activation of Sst-Chodl cells reveals that they actively promote widespread cortical synchronization and sleep-related…
