Multiple species display robust behavioral variance among individuals due to different genetic, genomic, epigenetic, neuroplasticity and environmental factors. Behavioral individuality has been extensively studied in various animal models, including rodents and other mammals. Fish, such as zebrafish (Danio rerio), have recently emerged as powerful aquatic model organisms with overt individual differences in behavioral, nociceptive and other CNS traits. Here, we evaluate individual behavioral differences in mammals and fish, emphasizing the importance of cross-species analyses of intraspecies variance in experimental models of normal and pathological CNS functions.

哺乳动物和鱼类的种内行为差异的种间分析。

由于不同的遗传，基因组，表观遗传，神经可塑性和环境因素，多种物种在个体之间表现出强大的行为差异。行为个性已经在包括啮齿动物和其他哺乳动物在内的各种动物模型中得到了广泛研究。鱼，例如斑马鱼（Danio rerio），最近已成为强大的水生模型生物，在行为，伤害和其他中枢神经系统特征方面存在明显的个体差异。在这里，我们评估哺乳动物和鱼类的个体行为差异，强调在正常和病理中枢神经系统功能实验模型中进行种内差异的跨物种分析的重要性。
