Neural systems for orienting attention to the location of threat signals: An event-related fMRI study
2006
NeuroImage
Preserved Fulltext
We used event-related fMRI to determine how brain responses to a neutral visual target are influenced by the emotional expression of faces appearing at the same location during a covert orienting task. ...
Attention may reflexively shift towards the location of perceived threats, but it is still unclear how these spatial biases recruit the distributed fronto-parietal cortical networks involved in other aspects ...

this study, event-related potentials (ERPs) were used to ex- amine the time course of neural responses to facial fear stimuli (versus neutral) presented overtly (for 500 msec with con
scious attention) ...
DISCUSSION
Consistent with the view that neural systems give prece- dence to signals of potential danger, facial signals of fear were found to elicit increases in neural activity relative
to neutral across ...
