研究人员记录了40名受试者在观看赏心悦目和赏心悦目的照片时，在瓦楞纸肌和颧肌区域的面部肌电活动。分析表明，在观看令人愉快的照片时，左颧肌区域的肌电活动产生的能量最高，其次是右颧、左瓦楞肌和右瓦楞肌区域。在观看不愉快的照片时，左瓦楞肌区域的肌电活动产生的能量最高，其次是右瓦楞肌、左颧肌和右颧肌区域。进一步的统计分析表明，在观看不愉快的照片时，左皱襞区肌电活动产生的功率明显高于右皱襞区肌电活动。结果表明，在情绪表达过程中，左侧面部肌电活动强度大于右侧面部肌电活动强度。
40 subjects' facial electromyographic (EMG) activity at the corrugator and zygomatic muscle regions were recorded while they were viewing pleasant and unpleasant photographs. Analysis showed that the EMG activity at the left zygomatic muscle region generated the highest power, followed by the right zygomatic, left corrugator, and right corrugator muscle regions, while viewing pleasant photographs. The EMG activity at the left corrugator muscle region generated the highest power, followed by the right corrugator, left zygomatic, and right zygomatic muscle regions, while viewing unpleasant photographs. Further statistical analysis indicated that the EMG activities at the left corrugator region generated significantly higher power than those at the right corrugator region while viewing unpleasant photographs. It was concluded that the intensity of facial EMG activity on the left side of the face was stronger than the right side of the face during the process of emotional expression.
