Results Unlike the controls, the SAD group showed a trend toward significant correlations between baseline RMSSD and left anterior insula activity during neutral face processing ( R 2 = 0.118, β = -0.003, F= 3.886 , p = .058) and significant correlations with both left anterior insula and right amygdala activities during angry face processing ( R 2 = 0.157, β = -0.003, F = 5.415, p = .027 and R 2 = 0.135, β = -0.002, F = 4.360, p = .046, respectively).
