The efferent projections of the rat entopeduncular nucleus were examined by use of the anterogradely transported lectin Phaseolus vulgaris-leucoagglutinin (PHA-L). Injections of PHA-L into different parts of the entopeduncular nucleus resulted in a moderate number of labeled nerve fibers in the ipsilateral globus pallidus. The fibers displayed a heterogeneous morphology: some were of small caliber with few delicate varicosities, others were of medium caliber with several more bulbous nerve terminals. Restricted injections in the dorsal and ventral parts of the entopeduncular nucleus, respectively, showed that the dorsal part of the entopeduncular nucleus projects to the dorsal and rostral parts of the dorsal pallidum and the ventral part to the ventral and caudal parts.
利用顺行运输的凝集素菜豆白细胞凝集素(PHA-L)对大鼠内苍白球核的传出投射进行了研究。将PHA-L注射到内苍白球核的不同部位后,在同侧苍白球内发现了数量适中的标记神经纤维。这些纤维呈现出异质性形态:一些纤维直径较小,有少量细微的膨体,另一些纤维直径中等,有更多球状神经末梢。分别在内苍白球核的背侧和腹侧进行局限性注射,结果显示内苍白球核的背侧部分投射到背侧苍白球的背侧和吻侧部分,腹侧部分投射到腹侧苍白球的腹侧和尾侧部分。
