Injections of horseradish peroxidase into either the spinal cord or cerebellum label neurons in the gigantocellular and lateral reticular nuclei of the North American opossum. In order to determine if neurons which project to the spinal cord and cerebellum are intermingled in these two nuclei and if single neurons provide collaterals to both areas, we have employed fluorescent markers in double-labelling experiments. Our results show that reticular neurons innervating either the spinal cord or cerebellum are often close together and that a few provide collaterals to both areas. Neurons providing such collaterals are rare, however, comprising 2% or less of those innervating either target alone.
将辣根过氧化物酶注射到北美负鼠的脊髓或小脑中，会标记出巨细胞和外侧网状核中的神经元。为了确定投射到脊髓和小脑的神经元是否在这两个核中相互交织，以及单个神经元是否向这两个区域提供侧支，我们在双标记实验中使用了荧光标记。我们的结果表明，支配脊髓或小脑的网状神经元通常靠得很近，并且有少数向这两个区域提供侧支。然而，提供这种侧支的神经元很少见，仅占单独支配任一目标区域的神经元的2%或更少。
