Involvement of tuberomamillary histaminergic neurons in isoflurane anesthesia.

Luo T, Leung LS (2011) Involvement of tuberomamillary histaminergic neurons in isoflurane anesthesia. Anesthesiology 115(1):36-43. doi: 10.1097/ALN.0b013e3182207655

Summary: Although previous studies indicate that histaminergic neurotransmission may mediate reaction to general anesthesia, it is not clear whether the histominergic tuberomammilary nucleus (TMN) is involved. Rats received 250-ng infusions of orexin-SAP (Cat. #IT-20) into the TMN after which the righting reflex was assessed for several anesthetics. Loss of histaminergic neurons in the TMN only altered the effect of isoflurane – suggesting that the neural circuits involved in isoflurane anesthesia are different than circuits affected by propofol, pentobarbital, and ketamine.
