In this research, for the first time, we analyze the relationship between facial muscles and brain activities when human receives different dynamic visual stimuli. We present different moving visual stimuli to the subjects and accordingly analyze the complex structure of electromyography (EMG) signal versus the complex structure of electroencephalography (EEG) signal using fractal theory. Based on the obtained results from analysis, presenting the stimulus with greater complexity causes greater change in the complexity of EMG and EEG signals. Statistical analysis also supported the results of analysis and showed that visual stimulus with greater complexity has greater effect on the complexity of EEG and EMG signals. Therefore, we showed the relationship between facial muscles and brain activities in this paper. The method of analysis in this research can be further employed to investigate the relationship between other human organs’ activities and brain activity.

大脑和面部肌肉活动响应动态视觉刺激的关系解码

在这项研究中，我们首次分析了人类接受不同动态视觉刺激时面部肌肉与大脑活动的关系。我们向受试者呈现不同的移动视觉刺激，并使用分形理论分析肌电图 (EMG) 信号的复杂结构与脑电图 (EEG) 信号的复杂结构。根据分析获得的结果，呈现更复杂的刺激会导致 EMG 和 EEG 信号的复杂性发生更大的变化。统计分析也支持分析结果，并表明具有更大复杂性的视觉刺激对EEG和EMG信号的复杂性有更大的影响。因此，我们在本文中展示了面部肌肉与大脑活动之间的关系。
