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.
在一夫一妻制的草原田鼠（Microtus ochrogaster）和滥交的草甸田鼠（M. pennsylvanicus）中，研究了终纹床核（BST）和内侧杏仁核（MA）中加压素免疫反应性（AVP-ir）细胞及其向外侧隔区的AVP-ir投射。在两个物种中均发现了具有性别二态性的AVP-ir通路；雄性在BST和MA中的AVP-ir细胞比雌性更多，并且在外侧隔区的AVP-ir纤维也比雌性更密集。还发现了显著的物种差异。总体而言，草甸田鼠在BST和MA中的AVP-ir细胞比草原田鼠更多。然而，雄性草原田鼠在外侧隔区的AVP-ir纤维密度比雄性草甸田鼠更高。BST和MA中具有性别二态性的AVP-ir投射的物种差异与啮齿动物不同的生活策略和行为有关。
