The contrast of winning and losing in the 'good fanatic brain.' The image shows in warm colors the activity related to a significant victory. The blue scale represents the activation related to a significant loss; this pattern is congruent with the Mentalization Network, which suggests a rationalization process of the pain evoked by the losing scenario.
