摘要: 目的 探究经颅交流电刺激对脑电节律和认知功能的影响。方法 2017年12月,年轻健康志愿者60例均分为4组,分别采用20 Hz经颅交流电刺激行左侧运动皮层(C3)真/伪刺激或右侧初级运动皮层(C4)真/伪刺激,刺激前后受试者完成左/右手随机/规律按键4种手指序列按键任务,任务过程中采集脑电信号。观察反应时、正确率;脑电信号进行事件相关谱扰动多重差值分析。结果 C4真刺激后,受试者左手任务反应时缩短。结论 右侧初级运动皮层20 Hz经颅交流电刺激能提高左侧肢体运动序列学习能力。

Abstract: Objective To investigate the effects of transcranial alternating current stimulation (tACS) on electroencephalography (EEG) rhythm and cognitive function. Methods In December, 2017, 60 healthy young volunteers were divided into four groups equally, who accepted 20 Hz real or sham tACS on left C3 or right C4. They were asked to complete four types of finger sequence key pressing tasks (left/right hand random/regular key pressing) before and after stimulation, while the EEG signals were collected and the reaction time and accuracy were observed. EEG signals were analyzed with multiple difference analysis of event-related spectral perturbation. Results The reaction time of contralateral hand reduced after C4 real stimulation. Conclusion Right 20 Hz tACS can improve the learning of contralateral limb sequential movement.

Key words: transcranial alternating current stimulation, serial reaction time task, electroencephalography, motor learning, event-related spectral perturbation
