Analgesia is an important effect of volatile anaesthetics, for which the spinal cord is a critical neural target. However, how supraspinal mechanisms modulate analgesic potency of volatile anaesthetics is not clear. We investigated the contribution of the central amygdala (CeA) to the analgesic effects of isoflurane and sevoflurane. ⋯ The analgesic potencies of volatile anaesthetics are partially mediated by modulation of NALCN in CeAGABA neurones.
