Abstract: ［Abstract］Objective　To study the effects of neural stem cells transplantation on spinal nerves electrophysiology in subacute stage．Methods　15 femal adult rats were divided into three groups：sham operation group， merely spinal cord transsection group，and NSC transplantation group．The cortical somatosensory evoked potential（CSEP）and Motion Evoked Potential（MEP）were evaluated and the cortical motor area stimulation by electro-acupuncture was performed in the three groups．Results　Latency of CSEP and MEP of rats in NSC transplantation group was shorter than merely spinal cord transsection group．Neural stem cells transplantation led to hind limbs contraction after cortical motor area stimulation by electro-acupuncture．Conclusion　Neural stem cells transplantation can partially promotes the recovery of sensory nerve and motor nerve conduction of injured spinal cord.
