A Sleep-Specific Midbrain Target for Sevoflurane Anesthesia.

ABSTRACT: Sevoflurane has been the most widely used inhaled anesthetics with a favorable recovery profile; however, the precise mechanisms underlying its anesthetic action are still not completely understood. Here the authors show that sevoflurane activates a cluster of urocortin 1 (UCN1⁺ )/cocaine- and amphetamine-regulated transcript (CART⁺ ) neurons in the midbrain involved in its anesthesia. Furthermore, growth hormone secretagogue receptor (GHSR) is highly enriched in sevoflurane-activated UCN1⁺ /CART⁺ cells and is necessary for sleep induction. Blockade of GHSR abolishes the excitatory effect of sevoflurane on UCN1⁺ /CART⁺ neurons and attenuates its anesthetic effect. Collectively, their data suggest that anesthetic action of se
