Different types of neurons and fibres in the Commissura colliculi inferiores (CCI) of the rabbit are described using the Golgi rapid method. Neurons were classified according to soma shape, dendritic arborization and location within the commissure. Four main neuronal types were found i.e., (1) Vertical cells; (2) Multipolar cells; (3) Horizontal cells; (4) Small rounded cells. With exception of the latter, all neuron types could be divided into several cells varieties. Four different types of fibres were observed within the CCI: a) myelinated commissural fibres; b) fibres from the dorsal cortex of the colliculus; c) fibres from the dorsal PAG nucleus; d) intrinsic fibres from the neurons of the CCI. The results of this study demonstrate the non-homogeneous structure of the CCI, which was earlier shown in the cat and rat. Also, a division of some of the commissural neurons into local and projecting neurons, based on their axonal branching pattern is suggested.
采用高尔基快速染色法对家兔下丘连合（CCI）中不同类型的神经元和纤维进行了描述。根据神经元的胞体形状、树突分支和在连合中的位置对其进行分类。发现了四种主要的神经元类型，即：（1）垂直细胞；（2）多极细胞；（3）水平细胞；（4）小圆形细胞。除了后者，所有神经元类型都可分为几个细胞变种。在CCI内观察到四种不同类型的纤维：a）有髓连合纤维；b）来自下丘背侧皮质的纤维；c）来自背侧中脑导水管周围灰质核的纤维；d）来自CCI神经元的固有纤维。本研究结果表明，CCI结构不均一，这一点在猫和大鼠中已得到证实。此外，根据轴突分支模式，建议将一些连合神经元分为局部神经元和投射神经元。
