The hypothalamic neuropeptide oxytocin exerts analgesic effects, but the underlying pathways remain largely elusive. Here, the authors describe an analgesic pathway formed by oxytocin neurons projecting to the periaqueductal grey, where axonally released oxytocin activates oxytocin-receptor expressing GABA neurons and subsequently reduces pain-like behaviors in both female and male rats.
