Effects of oxytocin infusion on partner preferences for a same-sex cage-mate. A significant preference for huddling with the partner over the stranger was observed in the aCSF group, while OT inhibited the partner preference, and significantly less time was spent huddling with the partner in the OT group compared to the aCSF group. OTRA co-administration did not block the OT-induced inhibition of the partner preference, whereas V1aRA co-administration rescued the partner preference. *p < 0.05, **p < 0.001. aCSF: artificial cerebrospinal fluid (vehicle); OT: oxytocin (1 ng); OT + OTRA: oxytocin (1 ng) + oxytocin receptor antagonist (30 ng); OT + V1aRA: oxytocin (1 ng) + vasopressin receptor antagonist (30 ng).
