Parvalbumin-like immunoreactivity (PA-LI) has been studied in sections of the superior colliculus (SC) of the rat and its distribution compared to the patterns of acetylcholinesterase (AChE) and cytochrome oxidase (CO) staining. In the intermediate layers it was found that PA-LI is spatially associated with AChE only in the medial part of the SC, but assumes a complementary distribution further laterally. There was a positive correlation between PA-LI and CO. We conclude that the patterns of PA-LI and CO are not systematically related to collicular input known to be associated with the AChE-rich zones, but may reflect adherence to channel separation beyond the terminal fields of clustered afferents.
已对大鼠上丘（SC）切片中的类小白蛋白免疫反应性（PA-LI）进行了研究，并将其分布与乙酰胆碱酯酶（AChE）和细胞色素氧化酶（CO）染色模式进行了比较。在中间层发现，PA-LI仅在SC的内侧部分与AChE在空间上相关，但在更外侧呈现互补分布。PA-LI与CO之间存在正相关。我们得出结论，PA-LI和CO的模式与已知与富含AChE区域相关的丘系输入没有系统关联，但可能反映了在成簇传入终末场之外对通道分离的遵循。
