单侧运动皮质损伤引起对侧肢体和面肌瘫痪及僵直,由于损毁区域主要位于中央前回中部、下部和上部的背外侧部分,而靠近中线的部分及旁中央小叶区未被损毁,所以上肢的瘫痪程度比下肢严重。动物可用后肢站立,用健侧未瘫痪的前肢取食,能正常生活。模型症状与人类单瘫症状相似,并且稳定而持久。在应用移植促进功能恢复的研究中可能会有实用价值。 Unilateral motor cortex injury caused contralateral limb and facial paralysis and stiffness, the damage area is mainly located in the central anterior back central, lower and upper dorsolateral part of the part near the midline and the central lobular area is not damaged, so the upper limb Paralysis than the lower extremities. Animals can be used to stand hindlimbs, paralyzed with contralateral paraplegic forelimb feeding, to normal life. Symptoms of the model are similar to those of human hemiplegia and are stable and long-lasting. There may be practical value in the application of transplantation to promote functional recovery.
