虽然人们早就知道蝎子的前体神经节是由一个密集的动脉系统供应的，但这个网络的模式从未被详细描述和分析过。使用MicroCT与计算机辅助三维重建相结合，我们提供了第一个详细的描述的模式，动脉的前体神经节Brotheas granulatus（蝎子，Chactidae）和其他蝎子物种。蝎子的整个前体神经节是由前主动脉系统的主要动脉分支的动脉网络供应的。其中最突出的是九条跨神经节动脉，它们沿着身体的中线穿过神经块，并在末端（即在神经柱下方）分支分支成较小的动脉。这些动脉在周围的胞体和位于神经节中央的神经元结构之间网状成密集的网络。我们证明存在于前体神经节的蝎子的毛细血管系统的传入动脉，提供血淋巴进入神经节和传出动脉运输血淋巴出神经节。采用脊椎动物循环系统的结构定义，这种毛细血管网络也可以称为双极网（位于传入和传出动脉之间），类似于脊椎动物和一些棘皮动物中发现的那些。在蝎前体神经节的奇异网内，某些区域（即神经柱）的供应比其他区域更好。这里提供的结构信息，现在可以用于功能神经元的研究，以确定在复杂的蝎子神经系统中的各种neuropil的生理和计算意义。
Though it has long been known that the prosomal ganglion of scorpions is supplied by a dense system of arteries, the pattern of this network has never been described and analyzed in detail. Using MicroCT in combination with computer aided 3D-reconstruction we provide the first detailed description of the pattern of arteries in the prosomal ganglion of Brotheas granulatus (Scorpiones, Chactidae) and other scorpion species. The entire prosomal ganglion in scorpions is supplied by a network of arteries that branch off the major arteries of the anterior aorta system. The most prominent of these are the nine transganglionic arteries which run through the nerve mass along the midline of the body and branch terminally, i.e. below the neuropils, into smaller arteries. These arteries reticulate into a dense network between the surrounding somata and the centrally located neuropil structures of the ganglion. We demonstrate the presence in the prosomal ganglion of scorpions of a capillary system made up of afferent arteries which deliver hemolymph into the ganglion and efferent arteries which transport the hemolymph out of the ganglion. Adopting the structural definition used for vertebrate circulatory systems, this capillary network can also be termed a bipolar rete mirabile (located as it is between afferent and efferent arteries) analogous to those found in vertebrates and some echinoderms. Within the rete mirabile of the scorpion prosomal ganglion, some regions (i.e. neuropils) are better supplied than others. The structural information provided here can now be used in functional neuronal studies to determine the physiological and computational significance of the various neuropils in the complex scorpion nervous system.
