Abstract

Significance: Although millions of procedures are performed under general anesthesia every year, we do not fully understand the mechanisms underlying anesthesia. Orexin neurons in the hypothalamus form one of the centers in the central nervous system involved in sleep–wake control. The orexin system has also been implicated in anesthesia. In this study, we specifically activated orexin neurons via a designer receptor that is exclusively activated by a designer drug, to test how activation of orexin neurons affects anesthesia recovery. We found that orexin neuronal activation can speed up wakeup and improve pain control as well. Our study suggests that the orexin system has the potential as a target for drug discovery to facilitate postprocedural recovery.

  • Causal reactivation of some wake-promoting neurons during emergence has been explored with electrical, optogenetic, and chemogenetic methods in rodents and suggested in humans.

    “the causal reactivation of some wake-promoting neurons during emergence from the anesthetic state has been explored using approaches such as electrical stimulation, optogenetics, and chemogenetics [115–118] in rodents and suggested in humans [119].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
