Using functional magnetic resonance imaging, we measured amygdala reactivity to faces varying on emotional intensity in subjects with generalized social phobia (GSP) and matched healthy controls, and observed greater bilateral activation to high (vs. low) intensity expressions in the phobic group, suggesting that more arousing social-emotional cues contribute to limbic hyperactivity in GSP.
通过功能磁共振成像，我们测量了广泛性社交恐惧症（GSP）患者和匹配的健康对照者杏仁核对不同情绪强度面部表情的反应性，并观察到恐惧症组对高强度（相对于低强度）表情的双侧激活更强，这表明更具刺激性的社会情感线索会导致GSP患者边缘系统过度活跃。
