Social animal species present a vast repertoire of social interactions when encountering conspecifics. Reproduction-related behaviors, such as mating, parental care, and aggression, are some of the most rewarding types of social interactions and are also the most sexually dimorphic ones. This review focuses on rodent species and summarizes recent advances in neuroscience research that link sexually dimorphic reproductive behaviors to sexual dimorphism in their underlying neuronal circuits. Specifically, we present a few possible mechanisms governing sexually-dimorphic behaviors, by hypothalamic and reward-related brain regions. Sex differences in the neural response to social isolation in adulthood are also discussed, as well as future directions for comparative studies with naturally solitary species.

社交网络：对生殖行为，动机和对社会孤立的反应中性别差异的神经控制。

当遇到同种动物时，社交动物物种呈现出巨大的社交互动。与生殖有关的行为，例如交配，父母关怀和侵略，是社交互动中最有价值的类型，也是性取向最严重的一种。这篇综述的重点是啮齿动物，并总结了神经科学研究的最新进展，这些研究将性二形生殖行为与其潜在的神经元回路中的性二形联系起来。具体来说，我们提出了一些可能的机制，通过下丘脑和奖励相关的大脑区域来控制性二态行为。还讨论了成年后对社会孤立的神经反应中的性别差异，以及与自然孤独物种进行比较研究的未来方向。
