Iontophoretic injections of the fluorescent retrograde tract tracer, Fluoro-gold, into the entopeduncular nucleus of the rat (homologous to the internal segment of the primate globus pallidus) resulted in a substantial number of retrogradely labeled neurons in the ipsilateral globus pallidus (homologous to the external segment of the primate globus pallidus). In experiments confirming this projection, iontophoretic injections of the anterograde tract tracer, Phaseolus vulgaris-leucoagglutinin, in the globus pallidus resulted in dense fiber and terminal labeling in the ipsilateral entopeduncular nucleus. This projection is topographically organized in rostral-caudal, medial-lateral and dorsal-ventral orientations.
将荧光逆行示踪剂氟金通过离子电渗法注入大鼠的内苍白球核（与灵长类苍白球内侧段同源），结果在同侧苍白球（与灵长类苍白球外侧段同源）中发现了大量逆行标记的神经元。在证实这一投射的实验中，将顺行示踪剂菜豆白细胞凝集素通过离子电渗法注入苍白球，结果在同侧内苍白球核中出现了密集的纤维和终末标记。这一投射在前后、内外和背腹方向上呈拓扑学排列。
