The aim of this study was to analyse the high density EEG during movement execution guided by visual attention to reveal the detailed topographic distributions of delta and theta oscillations. Twenty right-handed young subjects performed a finger tapping task, paced by a continuously transited repeating visual stimuli. Baseline corrected power of scalp current density transformed EEG was statistically assessed with cluster-based permutation testing. Delta and theta activities revealed differences in their spatial properties at the time of finger tapping execution. Theta synchronization showed a contralateral double activation in the parietal and fronto-central regions, while delta activity appeared in the central contralateral channels. Differences in the spatiotemporal topography between delta and theta activity in the course of movement execution were identified on high density EEG.

本研究的目的是分析由视觉注意力引导的运动执行过程中的高密度 EEG，以揭示 delta 和 theta 振荡的详细地形分布。二十名右利手的年轻受试者执行手指敲击任务，由连续过渡的重复视觉刺激控制。头皮电流密度转换 EEG 的基线校正功率通过基于簇的排列测试进行统计评估。Delta 和 theta 活动在手指敲击执行时揭示了它们的空间属性差异。Theta 同步显示顶叶和额中央区域的对侧双重激活，而中央对侧通道中出现 delta 活动。
