Anterior PPA is the strongest locus of cross-decoding. A, Cross-decoding in anterior and posterior PPA of Penn students. Each subject's scene-selective PPA was divided into an anterior section contained within PHC and a posterior section outside of PHC. Cross-decoding performance was greater in the anterior section than in the posterior section, consistent with the result of the searchlight analysis. B, Scene selectivity in PHC predicts cross-decoding. The scatterplot depicts the relationship between scene selectivity (x-axis) and cross-decoding (y-axis) for voxels in the PHC. Scene selectivity was measured at each voxel as the group-level t statistic for a contrast of scenes greater than objects, and cross-decoding was measured as the t statistic observed when that voxel served as a searchlight center in the MVPA analysis of cross-decoding. Inspection of the results indicates that cross-decoding is strongest in searchlights surrounding the most scene-selective voxels.
