fMRI measures. Areas of significant hemodynamic responses obtained for the contrast comparing images of girls between the pre- and the posttest. The activation is superimposed on the individual brain of the patient. Statistical significance threshold: p ≤ .05 (uncorr.), spatial extend: 5 voxel. A masking procedure was applied, masking each comparison with the appropriate baseline contrast at p ≤ .05 (uncorr.) (for details see Additional file 1, 4. fMRI: data analysis). (A) Activation cluster in the right Hippocampus (entorhinal cortex), cytoarchitectonic probability: 90%, MNI-coordinates of the local maximum: x = 24 mm, y = 3 mm, z = -37 mm. (B) Activation cluster in the right middle orbital gyrus, MNI-coordinates of the local maximum: x = 16 mm, y = 64 mm, z = -12 mm. Red: Pretest > Posttest. Green: Posttest > Pretest.
