fMRI measures. Areas of significant hemodynamic responses obtained for the contrast comparing images of girls between the pre- and the posttest (A) and images of women between the pre- and the posttest (B). The activation is superimposed on the individual brain of the patient. Statistical significance threshold: p ≤ .01 (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). Red: Pretest > Posttest. Green: Posttest > Pretest.
