Amygdala responses to spider vs mushroom pictures. Increased activation in the right and left amygdala in phobic subjects was found regardless of perceptual load. Statistical parametric maps are overlaid on a T1 scan (radiological convention: left = right; y = -1). The plot shows the difference of parameter estimates (spider vs mushroom; mean and standard error) for the maximally activated voxel in the left amygdala.
