Fig. 3.

Graphic illustration of the temporal evolution of the response to disgusting food representations identified in Prader Willi syndrome patients. Statistic t values of the activations (axis y) are plotted against time (axis x) expressed as 2-s frames starting from stimulus onset (frame 1). The bold line in axis x indicates stimulus duration (8–10 s) of the disgusting scenes. Data from the 8 scenes were averaged to illustrate the activation cycle. The activation was measured using the t-values of the region coordinate in the cluster showing peak activation across the cycle (Supplementary Table 3).The error bars represent the standard error of the mean (SEM).
