Nasonia, a genus of parasitoid wasps, is a promising model system in the study of developmental and evolutionary genetics, as well as complex traits such as learning. Of these "jewel wasps", the species Nasonia vitripennis is widely spread and widely studied. To accelerate neuroscientific research in this model species, fundamental knowledge of its nervous system is needed. To this end, we present an average standard brain of recently eclosed naïve female N. vitripennis wasps obtained by the iterative shape averaging method. This "Jewel Wasp Standard Brain" includes the optic lobe (excluding the lamina), the anterior optic tubercle, the antennal lobe, the lateral horn, the mushroom body, the central complex, and the remaining unclassified neuropils in the central brain. Furthermore, we briefly describe these well-defined neuropils and their subregions in the N. vitripennis brain. A volumetric analysis of these neuropils is discussed in the context of brains of other insect species. The Jewel Wasp Standard Brain will provide a framework to integrate and consolidate the results of future neurobiological studies in N. vitripennis. In addition, the volumetric analysis provides a baseline for future work on age- and experience-dependent brain plasticity.

珠宝黄蜂标准大脑：女性Nasonia vitripennis脑的平均形状图谱和形态。

Nasonia是寄生蜂的一种，在研究发育和进化遗传学以及诸如学习之类的复杂性状方面，是一种很有前途的模型系统。在这些“珠宝黄蜂”中，Nasonia vitripennis物种被广泛传播和广泛研究。为了加速对该模型物种的神经科学研究，需要有关其神经系统的基础知识。为此，我们提出了一种通过迭代形状平均法获得的，最近被封闭的幼稚天竺葵女性N. vitripennis黄蜂的平均标准大脑。该“珠宝黄蜂标准脑”包括视神经叶（不包括椎板），前视神经结节，触角叶，侧角，蘑菇体，中央复合体以及中央脑中其余未分类的神经毛。此外，我们简要描述了这些定义明确的神经毛及其在N. vitripennis脑中的子区域。在其他昆虫物种的大脑中讨论了这些神经纤维的体积分析。珠宝黄蜂标准脑将提供一个框架，以整合和巩固未来在碳纤网中神经生物学研究的结果。此外，体积分析为以后有关年龄和经验的脑可塑性研究提供了基准。
