Greater pre to post BOLD response decreases in the right caudate (MNI: 18, 20, 5, Z = 3.66, k = 37; r = -0.59) in response to thin-models relative to average-weight models.

Scatter plots of relative activations.
(A) The positive correlation between change in putamen activation and change in body dissatisfaction (r = 0.64). (B) The positive correlation between change in caudate activation and change in body dissatisfaction (r = 0. 63). (C) The negative correlation between change in precuneus activation and change in thin-ideal internalization (r = -0.55).
