The organisation of corticofugal fibres within the basis pedunculi of rats was studied using wheat germ agglutinin-horseradish peroxidase as an orthograde tracer. Following cortical injections, labelled fibres were distributed within the cerebral peduncle in an orderly way. Fibres which originate from cells in the frontal cortex maintain a position in the ventromedial part of the basis pedunculi. Fibres from the occipital and temporal cortex travel in the most dorsolateral part. Somatosensory fibres travel between these two. The extent of labelled fibres within the peduncles is correlated with the relative density of corticopontine cells arising from different areas of the cerebral cortex.
使用小麦胚芽凝集素-辣根过氧化物酶作为顺行示踪剂，研究了大鼠大脑脚内皮质传出纤维的组织情况。在进行皮质注射后，标记的纤维以有序的方式分布在大脑脚内。起源于额叶皮质细胞的纤维在大脑脚基部的腹内侧部分保持一定位置。来自枕叶和颞叶皮质的纤维走行于最背外侧部分。躯体感觉纤维在这两者之间走行。大脑脚内标记纤维的范围与大脑皮质不同区域产生的皮质脑桥细胞的相对密度相关。
