Sex differences in how stress affects brain activity during face viewing.
Under stress, men tend to withdraw socially whereas women seek social support. This functional magnetic resonance imaging study indicates that stress also affects brain activity while viewing emotional faces differently for men and women. Fusiform face area response to faces was diminished by acute stress in men but increased by stress in women. Furthermore, among stressed men viewing angry faces, brain regions involved in interpreting and understanding others' emotions (the insula, temporal pole, and inferior frontal gyrus) showed reduced coordination with the fusiform face area and the amygdala, whereas the functional connectivity among these regions increased with stress for women. These findings suggest that stress influences emotional perception differently for men and women.
