采用正反行示踪技术，在光镜和电子显微镜下探讨了从黑质网状部（SNr）经红核（RN）到细胞网状结构（RFp）的可能途径。在对侧SNr背侧注射生物素化右旋胺（BDA）和在RFp注射霍乱毒素B亚基（CTb）后，许多CTb标记的神经元在RN背侧分布，在那里发现许多BDA标记的轴突终末来自同侧SNr。将BDA和小麦胚芽凝集素-辣根过氧化物酶（WGA-HRP）分别注射到大鼠脑背侧和大鼠脑背侧，发现BDA标记的同侧轴突与大鼠脑背侧WGA-HRP标记的对侧神经元的体细胞和树突发生突触接触。
A possible pathway from the substantia nigra pars reticulata (SNr) to the parvicellular reticular formation (RFp) via the red nucleus (RN) was examined light and electron microscopically by combining anterograde and retrograde tracing techniques. After contralateral injections of biotinylated dextranamine (BDA) into the dorsolateral part of the SNr and cholera toxin B subunit (CTb) into the RFp, many CTb-labelled neurones were distributed contralaterally in the dorsal part of the RN, where numerous BDA-labelled axon terminals originating from the ipsilateral SNr were found. After contralateral injections of BDA into the dorsolateral part of the SNr and wheat germ agglutinin-horseradish peroxidase (WGA-HRP) into the RFp, ipsilateral axons labelled with BDA were found to make synaptic contacts with the somata and dendrites of contralateral neurones labelled with WGA-HRP in the dorsal part of the RN.
