在筑巢过程中，雄性和雌性斑胸草雀（Taeniopygia guttata）的社会行为网络和多巴胺奖励系统中有几个区域是活跃的，这两个神经回路与社会行为有关。由于非肽类的中叶催产素和血管催产素以及神经递质多巴胺在鸟类的社会行为中起着重要的作用，我们验证了社会行为网络中的中叶催产素-血管催产素和多巴胺能神经元群在筑巢过程中分别处于活跃状态的假设。我们结合免疫组化对筑巢和非筑巢雄性和雌性斑胸草雀脑组织中的Fos（神经元活性的间接标记物）和缩叶催产素、中叶催产素或酪氨酸羟化酶进行了检测，并比较了这些神经元群体中Fos的免疫反应性和筑巢行为的变化。在所有三种类型的神经元群体中，Fos的免疫反应性随着筑巢的某些方面而增加：(i)与对照组相比，筑巢雀的中耳膜能神经元群体的免疫反应性更高；（ii）与造巢雄鼠拾取的物质数量和雄鼠与其配偶在巢中度过的时间长短有关，血管生成素神经元群的免疫反应性增加；（三）多巴胺能神经元群的免疫反应性与雄性筑巢雀与其配偶在巢中度过的时间长短有关。综上所述，这些发现为中膜能-血管能和多巴胺能系统在鸟类筑巢中的作用提供了证据。
During nest building in zebra finches (Taeniopygia guttata), several regions in the social behaviour network and the dopaminergic reward system, which are two neural circuits involved in social behaviour, appear to be active in male and female nest-building finches. Because the nonapeptides, mesotocin and vasotocin and the neurotransmitter, dopamine, play important roles in avian social behaviour, we tested the hypothesis that mesotocinergic-vasotocinergic and dopaminergic neuronal populations in the social behaviour network and dopaminergic reward system, respectively, are active during nest building. We combined immunohistochemistry for Fos (an indirect marker of neuronal activity) and vasotocin, mesotocin or tyrosine hydroxylase on brain tissue from nest-building and non-nest-building male and female zebra finches and compared Fos immunoreactivity in these neuronal populations with the variation in nest-building behaviour. Fos immunoreactivity in all three types of neuronal populations increased with some aspect of nest building: (i) higher immunoreactivity in a mesotocinergic neuronal population of nest-building finches compared to controls; (ii) increased immunoreactivity in the vasotocinergic neuronal populations in relation to the amount of material picked up by nest-building males and the length of time that a male spent in the nest with his mate; and (iii) increased immunoreactivity in a dopaminergic neuronal population in relation to the length of time that a male nest-building finch spent in the nest with his mate. Taken together, these findings provide evidence for a role of the mesotocinergic-vasotocinergic and dopaminergic systems in avian nest building.
