We have investigated the anatomical organization of the lower division of the central body in the brain of the locust Schistocerca gregaria. Bodian preparations, Golgi impregnations, and intracellular filling with Lucifer yellow have revealed that the lower division of the central body is organized into six horizontal layers and sixteen vertical columns. Neurons of the lower division of the central body have been classified into five types of tangential neuron (TL1-TL5) and two types of columnar neuron (CL1, CL2). TL1-TL4 neurons ramify in specific layers in the lower division of the central body and in the lateral triangle (TL1, TL2 neurons), the median olive (TL3 neurons), or the dorsal shell (TL4 neurons) of the lateral accessory lobe. TL5 neurons ramify in the protocerebral bridge, in the lateral accessory lobe, and in all layers of the lower division of the central body. The two types of columnar neurons have arborizations in the protocerebral bridge and in the lower division of the central body and project to the lateral triangle of the lateral accessory lobe (CL1 neurons) or to the lower subunit of the nodulus (CL2 neurons). Possible functional implications for the processing of neuronal information in the central complex are discussed.
我们研究了沙漠蝗（Schistocerca gregaria）大脑中中央体下部分的解剖结构。博迪安染色法、高尔基浸染法以及用荧光黄进行细胞内填充法显示，中央体下部分由六个水平层和十六个垂直柱组成。中央体下部分的神经元已被分为五种切向神经元（TL1 - TL5）和两种柱状神经元（CL1、CL2）。TL1 - TL4神经元在中央体下部分的特定层以及外侧三角区（TL1、TL2神经元）、中橄榄（TL3神经元）或外侧副叶的背壳（TL4神经元）中分支。TL5神经元在原脑桥、外侧副叶以及中央体下部分的所有层中分支。文中还讨论了中央复合体中神经元信息处理可能的功能意义。
