Abstract

After partial deafferentation of one of the hindlimbs changes of the cord dorsal potential and mass discharge from the anterior-lateral filament of the exposed spinal cord were studied after maximal recovery of function of the deafferented limb in adult cats. Neuronal activity in response to electrical stimulation of the dorsal roots was considerably higher on the deafferented side than on the intact one. This seems to be due to plastic properties of the c. n. s. responsible for the recovery of functions.

摘要

在成年猫一侧后肢部分传入神经切断后,待去传入神经支配肢体功能最大程度恢复后,研究了脊髓背根电位的变化以及暴露脊髓前外侧纤维束的大量放电情况。去传入神经支配侧对背根进行电刺激时的神经元活动明显高于未受损侧。这似乎是由于中枢神经系统的可塑性特性导致功能恢复。
