BOLD, sweat and fears: fMRI and skin conductance distinguish facial fear signals
LM Williams, P Das, B Liddell, G Olivieri, A Peduto… - …, 2005 - journals.lww.com
It is not known how the brain and autonomic systems interact during perception of facial
signals of danger. We recorded blood-oxygen-level-dependent (BOLD) activity using fMRI
and simultaneous skin conductance measures of autonomic arousal in healthy subjects.
Distinct response profiles were elicited for fear (enhanced arousal with amygdala activity),
anger (rapid onset, slow recovery arousal responses with anterior cingulate) and disgust
(delayed arousal responses with insula and basal ganglia activity). The findings suggest that …
