The axonal pathways of spinal neurons were studied in the cat using Ramón y Cajal's silver method. The cells of the ventral group of the nucleus supraspinalis contribute to the ventral roots of C1 and the cells of the dorsal group send their axons to the contralateral ventral funiculus. The cells of lamina VII send their axons to the ipsilateral lateral or ventrolateral funiculus. The subnucleus ventralis of the nucleus medullae oblongatae centralis sends axons to the lateral funiculus or to the ventral roots of C1. The cells of lamina V send their axons to the lateral funiculus and the contralateral ventral funiculus. The cells of lamina VII send their axons to the ipsilateral lateral funiculus and to the contralateral ventral funiculus. Numbers of spinal border cells were were observed in lamina IX at the level of the cervical and lumbar enlargement. It was found that the cell groups which were classified cytoarchitectonically contained numbers of different types of cells as judged by their axonal pathways.
