杏仁核在效价和觉醒过程中的作用是一个有争议的问题。使用事件相关的功能性磁共振成像，我们测试了在注意力分散过程中，杏仁核的价特异性效应。受试者在前景中参与了一项匹配任务，其中包括中性图片，以及与唤醒相匹配的消极和积极图片。负性图片比中性或正性图片引起更强的杏仁核激活，提示在注意负荷下杏仁核有价特异性反应。
The role of the amygdala for the processing of valence and arousal is a matter of debate. Using event-related functional magnetic resonance imaging, we tested valence-specific amygdala effects during attentional distraction. Subjects attended to a matching task in the foreground of neutral pictures, and of negative and positive pictures matched for arousal. Negative pictures elicited stronger amygdala activation than neutral or positive pictures, suggesting valence-specific amygdala responses under attentional load.
