J Anat. 1976 Sep;122(Pt 1):169-75.

The development of the dorsal funiculus of the human cord is described from the second month to the end of the fourth. 2. The fasciculus cuneatus arises as a distinct bundle of fibres near the mid-line in the ninth week. This gradually spreads laterally, and to it is joined the more medial fasciculus gracilis. 3. The original embryonic dorsal marginal layer is displaced laterally, and may possibly become the dorsolateral tract adjacent to the dorsal horn. 4. The appearance of the future 'epicritic' pathway is accompanied by a marked wave of differentiation in cervical and thoracic ganglia. 5. The implications of these findings are discussed in relation to the problems of peripheral and central factors in nervous development.

描述了人类脊髓背侧索从第二个月到第四个月末的发育情况。2. 楔束在第九周时作为一束明显的纤维束出现在中线附近。它逐渐向外侧扩展，更内侧的薄束与之相连。3. 原始的胚胎背侧边缘层向外侧移位，可能会变成与背角相邻的背外侧束。4. 未来“精细感觉”通路的出现伴随着颈神经节和胸神经节明显的分化浪潮。5. 结合神经发育中周围和中枢因素的问题，对这些发现的意义进行了讨论。
