By means of retrograde labeling with WGA-HRP, and anterograde Wallerian degeneration, the propriospinal connections of the first three cervical myelomeres of the rat have been studied. These cervical segments project to the caudal ones, at least as far as L4 (the last segment studied). These descending fibres arise from neurons located in the deeper laminae of the dorsal horn, mainly in laminae V-VII. They run bilaterally, but with ipsilateral predominance, principally in the cervical cord. The course of the descending fibres is predominantly intragriseal for the cervical segments, and in the pars dorsomedialis of the funiculus lateralis for the caudal segments. The laminae in what the grat part of these descending fibres project are, mainly, VII, V and VIII.
通过用WGA-HRP进行逆行标记以及顺行性华勒氏变性，对大鼠颈髓前三节段的脊髓固有连接进行了研究。这些颈段投射到尾侧节段，至少延伸到L4（研究的最后一个节段）。这些下行纤维起源于位于背角深层板层的神经元，主要在板层V-VII。它们双侧走行，但以同侧为主，主要在颈髓。下行纤维在颈段的走行主要在灰质内，在尾侧节段则在外侧索的背内侧部。这些下行纤维大部分投射的板层主要是VII、V和VIII。
