Activation associated with altered interaction of emotion processing and motor control in conversion disorder.

a) Activation of left amygdala during simultaneous passive movement of right affected hand and the presentation of sad faces controlled for visual input (calm faces) in patients as compared to controls [(sad-affected > calm-affected) × (patients > controls)].

b) Activation of left amygdala resulting from a three way interaction contrast with patients vs. controls, showing syndrome specificity of amygdala activation [(sad-affected > calm-affected) × (sad-unaffected > calm-unaffected) × (patients > controls)]. For presentation purposes the statistical maps were thresholded at p < 0.005 unc. Color bar represents T-scores. The position on y-axis in the MNI-space is indicated above each coronal slice. The activation is displayed on the MRIcron template.
