Exploring phylogeny to find the function of sleep

RC Anafi, MS Kayser, DM Raizen - Nature Reviews Neuroscience, 2019 - nature.com
During sleep, animals do not eat, reproduce or forage. Sleeping animals are vulnerable to
predation. Yet, the persistence of sleep despite evolutionary pressures, and the deleterious …

Dynamic functional connectivity in the static connectome of Caenorhabditis elegans

SW Flavell, A Gordus - Current opinion in neurobiology, 2022 - Elsevier
A hallmark of adaptive behavior is the ability to flexibly respond to sensory cues. To
understand how neural circuits implement this flexibility, it is critical to resolve how a static …

Neuropeptide Y regulates sleep by modulating noradrenergic signaling

C Singh, J Rihel, DA Prober - Current Biology, 2017 - cell.com
Sleep is an essential and evolutionarily conserved behavioral state whose regulation
