The development of functional neuroimaging of emotion holds the promise to enhance our understanding of the biological bases of affect and improve our knowledge of psychiatric diseases. However, up to this point, researchers have been unable to objectively, continuously and unobtrusively measure the intensity and dynamics of affect concurrently with functional magnetic resonance imaging (fMRI). This has hindered the development and generalizability of our field. Facial electromyography (EMG) is an objective, reliable, valid, sensitive, and unobtrusive measure of emotion. Here, we report the successful development of a method for simultaneously acquiring fMRI and facial EMG. The ability to simultaneously acquire brain activity and facial physiology will allow affective neuroscientists to address theoretical, psychiatric, and individual difference questions in a more rigorous and generalizable way.
情感功能神经影像学的发展有望增强我们对情感生物学基础的理解，并提高我们对精神疾病的认识。然而，到目前为止，研究人员还无法客观、连续、非侵入性地同时测量功能磁共振成像（fMRI）时的情感强度和动态变化。这阻碍了我们这一领域的发展和推广。面部肌电图（EMG）是一种客观、可靠、有效、敏感且非侵入性的情感测量方法。在这里，我们报告了一种成功开发的同时获取 fMRI 和面部 EMG 的方法。同时获取大脑活动和面部生理学的能力将使情感神经科学家能够以更严格和更具普遍性的方式来解决理论、精神疾病和个体差异方面的问题。
