Abstract
We investigated anger-related variability in the BOLD fMRI response to crude/masked and detailed/unmasked fearful faces. Anger expression positively covaried with amygdala activation to crude fear, while trait anger negatively covaried with amygdala responses to detailed fear. This differential processing may trigger aggression without the subsequent inhibition associated with distress cues.
