中枢复合体(central complex, CX)是昆虫脑中线的一组神经丸,由原脑桥(protocerebral bridge, PB)、中央体上部(upper division, CBU)和下部(lower division, CBL)以及一对球状结节组成。它接受来自视觉系统的重要输入,在动物的空间定向中起着重要作用。CX的垂直切片和水平层由柱状、切向和桥状神经元组成。虽然已经详细分析了桥状和柱状神经元,特别是在果蝇和沙漠蝗虫中,但对切向细胞组织的理解仍然是初级的。为进一步研究荒漠蝗CX的切向神经元形态,为今后的功能研究奠定基础。细胞内染料注射显示43个不同类型的切向神经元,8个PB, 5个CBL, 24个CBU, 2个结节,4个支配多个亚结构。这些神经元的细胞体分布在细胞体表面的11个不同的簇中。从细尾和珠状尾的存在判断,这些神经元绝大多数向CX提供输入,特别是来自外侧复合体(LX)、上原脑、后坡和其他周围的脑区,但不是直接来自蘑菇体。连接主要是亚单位的,部分是层特异性的。没有发现CBU和CBL之间的直接联系。相反,这两个细分与前列腺和结节的不同层平行连接。
The central complex (CX) comprises a group of midline neuropils in the insect brain, consisting of the protocerebral bridge (PB), the upper (CBU) and lower division (CBL) of the central body and a pair of globular noduli. It receives prominent input from the visual system and plays a major role in spatial orientation of the animals. Vertical slices and horizontal layers of the CX are formed by columnar, tangential, and pontine neurons. While pontine and columnar neurons have been analyzed in detail, especially in the fruit fly and desert locust, understanding of the organization of tangential cells is still rudimentary. As a basis for future functional studies, we have studied the morphologies of tangential neurons of the CX of the desert locustSchistocerca gregaria. Intracellular dye injections revealed 43 different types of tangential neuron, 8 of the PB, 5 of the CBL, 24 of the CBU, 2 of the noduli, and 4 innervating multiple substructures. Cell bodies of these neurons were located in 11 different clusters in the cell body rind. Judging from the presence of fine versus beaded terminals, the vast majority of these neurons provide input into the CX, especially from the lateral complex (LX), the superior protocerebrum, the posterior slope, and other surrounding brain areas, but not directly from the mushroom bodies. Connections are largely subunit‐ and partly layer‐specific. No direct connections were found between the CBU and the CBL. Instead, both subdivisions are connected in parallel with the PB and distinct layers of the noduli.
