Amygdala reactivity to neutral stimuli and trait anxiety. A. Scatterplot showing the individual trait anxiety measurements plotted against the amygdala reactivity to neutral stimuli. The decreased amygdala activation to neutral stimuli, indicating higher baseline amygdala activation, was associated with higher levels of trait anxiety (r = −0.36, P = 0.048). B. The group of participants who reported higher trait anxiety than the median showed marginally significant de‐activation in the amygdala to neutral faces (Z = 1.32, P = 0.061), whereas the group of participants who reported lower trait anxiety showed increased activation in the amygdala to neutral faces (Z = 1.51, P = 0.022).
