Summary: New research uncovers how a hormonally tuned brain circuit in mice governs sex-specific mating behaviors. Scientists identified a subset of neurons in the prefrontal cortex that integrate oxytocin, ovarian hormones, and social cues to modulate sexual receptivity in females and suppress mating interest in males. Activating these neurons made non-fertile females receptive, while silencing them during estrus stopped their …
