在日本猕猴（Macaca fuscata）上研究了辅助运动区（SMA）向红核的直接投射。顺行示踪剂，辣根过氧化物酶结合麦胚凝集素（WGA-HRP），注射到不同地区的SMA后，皮质内微刺激映射。后WGA-HRP注射到orofacial，前肢，或后肢区域的SMA，顺行标记的轴突终末被发现，分别在内侧，中间，或外侧部分的小细胞部分的红核，双侧同侧优势。结果表明，来自SMA的皮质红核投射具有清晰的躯体定位排列。
Direct projections from the supplementary motor area (SMA) to the red nucleus were investigated in the Japanese monkey (Macaca fuscata). The anterograde tracer, horseradish peroxidase conjugated to wheat germ agglutinin (WGA-HRP), was injected into various regions of the SMA after intracortical microstimulation mapping. After WGA-HRP injection into the orofacial, forelimb, or hindlimb region of the SMA, anterogradely labeled axon terminals were found, respectively, in the medial, intermediate, or lateral portion of the parvocellular part of the red nucleus, bilaterally with an ipsilateral predominance. The results indicate the clear somatotopical arrangement of corticorubral projections from the SMA.
