Recent evidence indicates that general anesthesia and sleep-wake behavior share some overlapping neural substrates. GABAergic neurons in the central amygdala (CeA) have a high firing rate during wakefulness and play a role in regulating arousal-related behaviors. The objective of this study is to investigate whether CeA GABAergic neurons participate in the regulation of isoflurane general anesthesia and uncover the underlying neural circuitry. ⋯ Our results suggest that CeA GABAergic neurons play a role in general anesthesia regulation, which facilitates behavioral and cortical emergence from isoflurane anesthesia through the GABAergic CeA-BF pathway.
