研究了单配型草原田鼠（Microtus ochrogaster）和混杂草甸田鼠（M. pennaculicus）。在这两个物种中发现了性二态的AVP-IR通路，男性有更多的AVP-IR细胞在BST和MA，以及致密的AVP-IR纤维在侧隔，比女性。总体而言，草甸田鼠的BST和MA中的AVP免疫阳性细胞比草原田鼠多。雄性草原田鼠，然而，有一个较高的密度比雄性草甸田鼠的侧隔的AVP免疫反应纤维。种属间在BST和MA的性二态性AVP-ir投射的差异与啮齿动物不同的生存策略和行为有关。
Vasopressin-immunoreactive (AVP-ir) cells in the bed nucleus of the stria terminalis (BST) and medial amygdaloid nucleus (MA) and their AVP-ir projections to the lateral septum were studied in monogamous prairie voles (Microtus ochrogaster) and promiscuous meadow voles (M. pennsylvanicus). A sexually dimorphic AVP-ir pathway was found in both species; males had more AVP-ir cells in the BST and MA, as well as denser AVP-ir fibers in the lateral septum, than did females. A significant species difference was also found. Overall, meadow voles had more AVP-ir cells in the BST and MA than did prairie voles. Male prairie voles, however, had a higher density of AVP-ir fibers in the lateral septum than male meadow voles. The species difference in the sexually dimorphic AVP-ir projections in the BST and MA is implicated in the rodents' different life strategy and behavior.
