在这里，我们描述了游荡蜘蛛Cupiennius Salei脑中弓形体的神经元组织。基于生长抑素、直肠球蛋白和甲壳动物心脏活性多肽(CCAP)免疫组织化学，详细分析了这一主要大脑中枢的内部解剖。在图形重建中显示了突出的神经元特征。染色结果显示，弓状体神经结构由几个不同的层组成，其中一些由排列成柱状、栅栏状阵列的神经末梢组成。蜘蛛弓形身体的解剖结构与四胞蛛原脑的中央复合体相比，既有相似之处，也有不同之处。讨论了支持和反对海龟类弓形体和四龙纲中心复合体可能同源的争论，以及它们对节肢动物大脑进化理解的影响。(C)2011爱思唯尔有限公司。保留所有权利。
Here we describe the neuronal organization of the arcuate body in the brain of the wandering spider Cupiennius salei. The internal anatomy of this major brain center is analyzed in detail based on allatostatin-, proctolin-, and crustacean cardioactive peptide (CCAP)-immunohistochemistry. Prominent neuronal features are demonstrated in graphic reconstructions. The stainings revealed that the neuroarchitecture of the arcuate body is characterized by several distinct layers some of which comprise nerve terminals that are organized in columnar, palisade-like arrays. The anatomy of the spider's arcuate body exhibits similarities as well as differences when compared to the central complex in the protocerebrum of the Tetraconata. Arguments for and against a possible homology of the arcuate body of the Chelicerata and the central complex of the Tetraconata and their consequences for the understanding of arthropod brain evolution are discussed.
