Abstract | The amygdala is a subcortical medial temporal lobe structure that is widely thought to be involved in processing emotional information1. Amygdala dysfunction and abnormal attention to affective events have been commonly observed in anxiety disorders2. Characterizing how the amygdala interacts with other brain regions to influence attention in healthy adults could prove useful in developing a better understanding of the mechanisms underlying these illnesses. This paper will primarily review evidence from human neuroimaging studies that have examined a potential role for the amygdala in emotion-attention interactions.
