• 中文摘要： 本研究以HRP逆行性追綜法和順行性放射物質追綜法來研究台灣彌猴紅核脊髓徑的情形。結果發現台灣彌猴的紅核中投射到脊髓的神經元有局在性的組識情形。位於較內背側紅核內的神經元投射到較吻段的脊髓，而位於較腹外側紅核內的神經元則投射到較尾段的脊髓。這種紅核向脊髓的投射是雙側性的，但以對側的投射為主。本實驗的結果證明了台灣彌猴中紅核脊髓徑的存在。
• 英文摘要： Neurons projecting from the red nucleus to the spinal cord in the Formosan monkey were identifiedwith retrograde horseradish peroxidase and tritiated proline and fucose antegrade autoradiographic tracingmethods. A topographic organization of projections from the red nucleus to the spinal cord was demon-strated. Medial and dorsal portions of the rostral red nucleus projected to the rostral half of the spinalcord. Neurons in the ventrolateral part of the red nucleus emitted fibers which terminated in the caudalhalf of the spinal cord. The spinal projections from the red nucleus are bilateral, but contralateral pro-jection is dominant. These results indicated a well developed rubrospinal tract existence in the Formosanmonkey.
