Figure 3.

Cortical maps showing the difference in posterior probabilities of FPCN regions to be active given topic segregation and when given no topic segregation queries. We mask out brain voxels that are not part of the FPCN. The difference between posterior probabilities is defined as $\mathrm{\Delta }=\mathbf{P}[\text{VoxelReported}(x,y,z)|\text{SingleTopicAssociation}(t)]-\mathbf{P}[\text{VoxelReported}(x,y,z)|\text{TopicAssociation}(t)]$.
