Labeled cells were consistently found in region ⅹ which was also the area of dense labeling of terminal arborization, suggesting that this region plays a remarkable role in intersegmental connection. Ⅹ区标记细胞恒定,标记终支也较密集,提示该区在脊髓节段间的联系方面起着一定的作用。
The close approximation of labeled terminal arborization and labeled cells signifies direct intersegmental feedback circuit. 标记细胞旁有标记终支说明脊髓节段间有着反馈联系。
