- 中文摘要: The location, caudal extent, sites and mode of termination of tectospinal fibershave been studied by silver impregnation method of Nauta in 24 adult albino ratsfollowing stereotaxic lesions in the superior and inferior colliculi. Only the formerprojects to the spinal cord. The degenerating tectospinal fibers are completelycrossed and confined to the upper cervical segments of the cord. The degeneratingtectospinal fibers terminate mainly in the medial part of the ventral gray matter ofthe cord, corresponding in position to those in Rexed's lamina VIII in the cat.The degenerating tectospinal fibers appear to form axosomatic as well as axodend-ritic synapses with large and small neurons within the lamina of termination. Nofibers terminate directly on the motoneurons.
