情感功能神经成像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，研究人员还无法同时使用功能磁共振成像（fMRI）客观、连续、不显眼地测量情感的强度和动态。这阻碍了我们领域的发展和推广。面部肌电图（EMG）是一种客观、可靠、有效、敏感和不显眼的情绪测量方法。在这里，我们报告了一种同时获取功能磁共振成像和面部肌电图的方法的成功发展。同时获得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可推广的方式解决理论、精神和个体差异问题。(C) 2011爱思唯尔公司版权所有。
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.
