The pioneering work of Duchenne (1862/1990) was replicated in humans using intramuscular electrical stimulation and extended to another species (Pan troglodytes: chimpanzees) to facilitate comparative facial expression research. Intramuscular electrical stimulation, in contrast to the original surface stimulation, offers the opportunity to activate individual muscles as opposed to groups of muscles. In humans, stimulation resulted in appearance changes in line with Facial Action Coding System (FACS) action units (AUs), and chimpanzee facial musculature displayed functional similarity to human facial musculature. The present results provide objective identification of the muscle substrate of human and chimpanzee facial expressions- data that will be useful in providing a common language to compare the units of human and chimpanzee facial expression.
杜兴(1862/1990)的开创性工作通过肌内电刺激在人类身上得到了复制,并扩展到另一个物种(黑猩猩:Pan troglodytes),以促进比较面部表情研究。与最初的表面刺激相比,肌内电刺激提供了激活单个肌肉而非肌肉群的机会。在人类中,刺激导致的外观变化与面部动作编码系统(FACS)动作单元(AUs)一致,并且黑猩猩的面部肌肉组织显示出与人类面部肌肉组织的功能相似性。目前的结果提供了对人类和黑猩猩面部表情肌肉基质的客观识别——这些数据将有助于提供一种通用语言来比较人类和黑猩猩面部表情的单元。
