父亲和非父亲的投票（田鼠）有不同的精氨酸加压素（AVP）抗催产素（OT）受体模式的扩展杏仁核，神经通路与父母的行为。使用受体放射自显影术，作者研究了AVP和OT受体模式是否与兼性父系行为在性和父母经验不足或经验丰富的草甸票（田鼠pennsylvania）。有经验的，在没有经验的，男性有较少的AVP结合在外侧隔（LS），更多的AVP结合在前嗅核（AON），和更多的OT结合在AON，床核的终纹，LS，和外侧杏仁核。因此，特定的AVP受体模式，这与父亲的照顾，在一贯的父亲投票，也可能与父亲的照顾（当存在），在典型的非父亲的物种。这项研究还证明了雄性哺乳动物中OT受体模式与父系状态之间的可能关系。
Paternal and nonpaternal votes (microtus) have different arginine-vasopressin (AVP) anti oxytocin (OT) receptor patterns in the extended amygdala, a neural pathway associated with parental behavior. Using receptor autoradiography, the authors examined whether AVP and OT receptor patterns were associated with facultative paternal behavior in either sexually and parentally inexperienced or experienced meadow votes (Microtus pennsylvanicus). Experienced, in contrast to inexperienced, males had less AVP binding in the lateral septum (LS), more AVP binding in the anterior olfactory nucleus (AON), and more OT binding in the AON, bed nucleus of the stria terminalis, LS, and lateral amygdala. Thus, specific AVP receptor patterns, which co-occur with paternal care in consistently paternal votes, also may be associated with paternal care (when present) in typically nonpaternal species. This study also demonstrated a possible relationship between OT receptor patterns and paternal state in male mammals..
