Abstract

We studied the pattern of stepping in cats, before and after the placement of lesions in the corticospinal system. We found a deficit after the lesions, which was characterized by increased extension of the involved hindlimbs during the stance (E2--E3) phase of the step cycle. This deficit lasted two weeks or less. It may reflect loss of inhibitory influences upon extensor motoneuron pools.

摘要

我们研究了猫在皮质脊髓系统损伤前后的迈步模式。我们发现损伤后出现了一种缺陷，其特征是在步周期的站立（E2 - E3）阶段受累后肢的伸展增加。这种缺陷持续两周或更短时间。它可能反映了对伸肌运动神经元池的抑制性影响的丧失。
