Two of the targets of the ipsilateral descending pathway from the superior colliculus are the cuneiform area (immediately ventral to the inferior colliculus), and the dorsolateral basilar pons. The cells of origin of the projections to these targets in rat were studied with a retrograde double-labelling technique, using the fluorescent tracers True blue and Diamidino yellow. Although many tectal cells were single-labelled by injections into basilar pons or the cuneiform area, less than 5% were double-labelled. The two projections thus appear to arise mainly from separate populations of cells within the superior colliculus.
上丘同侧下行通路的两个靶点是楔状核区（紧位于下丘腹侧）和脑桥背外侧基底。采用荧光示踪剂真蓝和双脒基黄，运用逆行双重标记技术，对大鼠中投射至这些靶点的细胞起源进行了研究。尽管通过注射到基底脑桥或楔状核区，许多顶盖细胞被单标记，但少于5%的细胞被双重标记。因此，这两条投射通路似乎主要起源于上丘内不同的细胞群。
