Functional MRI shows brain activity prompted by fanaticism
By Kate Madden Yee
Functional MRI shows brain activity sparked by fanaticism, according to a presentation to be delivered at the upcoming RSNA meeting.
November 21, 2023
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.
