We confirmed the formation of an aberrant ipsilateral corticospinal tract after unilateral cerebral cortical ablation during the neonatal period in rat. This tract was studied using anterograde horseradish peroxidase (HRP) tracing. Ramifications of the axons in the pyramidal tract were found to contribute to the ipsilateral tract at the level of the pyramidal decussation, suggesting that ramification of immature axons play an important role in the formation of the ipsilateral corticospinal tract.
我们证实在新生大鼠出生后单侧大脑皮质切除术后形成了异常的同侧皮质脊髓束。使用顺行辣根过氧化物酶（HRP）示踪法对该束进行了研究。发现在锥体交叉水平，锥体束中的轴突分支对同侧束有贡献，这表明未成熟轴突的分支在同侧皮质脊髓束的形成中起重要作用。
