The adaptive threat bias in anxiety: amygdala–dorsomedial prefrontal cortex coupling and aversive amplification
OJ Robinson, DR Charney, C Overstreet, K Vytal… - Neuroimage, 2012 - Elsevier
Functionally, anxiety serves to increase vigilance towards aversive stimuli and improve the
ability to detect and avoid danger. We have recently shown, for instance, that anxiety …

The (neuro) cognitive mechanisms behind attention bias modification in anxiety: proposals based on theoretical accounts of attentional bias
Recently, researchers have investigated the causal nature of attentional bias for threat (AB)
in the maintenance of anxiety disorders by experimentally manipulating it. They found that …

Functional and structural amygdala–anterior cingulate connectivity correlates with attentional bias to masked fearful faces
An attentional bias to threat has been causally related to anxiety. Recent research has
linked nonconscious attentional bias to threat with variability in the integrity of the amygdala …
