摘要： 目的探讨单侧电刺激肢体运动对中枢神经系统的影响。方法8 名健康男性右利腿志愿者，电刺激诱导右踝背屈运动，同时进行功能磁共振成像扫描。结果电刺激右踝背屈运动主要激活双侧的初级躯体运动区、双侧初级躯体感觉区、双侧次级躯体感觉区、双侧扣带回、同侧运动前区、对侧运动辅助区。结论单侧肢体电刺激引起的双侧大脑皮质的变化。

Abstract: Objective To investigate the effect of unilateral electric stimulation of lower limbs movement on central nervous system. Methods 8 right-footed healthy men accepted electrical stimulation to evoke dorsiflexion of the right ankle, while the cerebral cortex activations were observed with functional magnetic resonance imaging. Results For electrical stimulation evoked contraction task, the significant activations were observed in the bilateral primary motor cortex, primary sensory area, secondary somatosensory cortex, cingulated gyrus; ipsilateral premotor area and contralateral supplementary motor area. Conclusion Unilateral electrical stimulation may result in activations of bilateral cerebral cortex.
