脑纳米肽精氨酸、血管生成素和异产素被认为参与了硬骨鱼的社会和生殖行为的调节。我们研究了四对原生假丑海葵Amphiprion ocellaris(Cuvier，1830)脑内精氨酸血管生成素和异生素神经元的免疫反应性。在450天的配对后，每个人的社会地位都可以通过体重来明确区分。居民-入侵者模型试验表明，优势个体比从属个体更倾向于表现争斗行为，但配对不能按社会等级诱导性别分化(即性腺指数和类固醇含量没有显著差异，两种社会等级个体的性腺都是卵巢)。然而，优势个体在大细胞层的精氨酸催产素神经元和在脑视前区(POA)的小细胞层中的异托品神经元的数量比从属个体大。精氨酸催产素和异催产素神经元在POA各层表现出不同的投射模式：在大细胞层，纤维支配端脑内侧区和中脑被盖，而在其他层则不支配。这些结果表明，海参脑内的血管催产素和异催产素神经元调节社会行为，并具有不同的作用。
The brain nanopeptides arginine vasotocin and isotocin are considered to be involved in the regulation of social and reproductive behavior in teleosts. We investigated the immunoreactivity of brain arginine vasotocin and isotocin neu- rons in four pairs of the protandrous false clown anemonefish Amphiprion ocellaris (Cuvier, 1830). After 450 days of pairing, the social rank of each individual was clearly distinguishable by body mass. The resident-intruder model test re- vealed that dominant individuals tended to display agonistic behavior more frequently than subordinate individuals, yet pairing failed to induce sex differentiation by social rank (i.e., gonadosomatic index and steroid profiles did not differ sig- nificantly and the gonads were ovotestes in both social rank individuals). However, dominant individuals had a larger size of arginine vasotocin neurons in the magnocellular layer and a greater number of isotocin neurons in the parvocellular layer of the brain preoptic area (POA) than did subordinate individuals. Arginine vasotocin and isotocin neurons of each layer of the POA showed different projection patterns: in the magnocellular layer, the fibers innervated the medial zone of the telencephalon and the mesencephalic tegmentum, but not in other layers. These results suggest that vasotocin and iso- tocin neurons in the brain of A. ocellaris regulate social behavior and have different roles.
