Figure 2. PFC correlations between FA and less complex reasoning.

TBSS (A) and probabilistic tractography (B, C) results are displayed for reasoning in low-performing individuals. A: Reasoning in low-performing participants relies on white matter subjacent to the left anterior (aBA6) and left posterior (pBA6) BA6 (PFC-only analysis; p = 0.08, corrected). B, C: Pathways tracked from aBA6 (B) and pBA6 (C) are shown overlaid onto MNI152_T1_1 mm standard space (radiological convention). The color code represents the number of participants for which connectivity distributions were found in a given voxel with warm colors indicating larger and cold colors indicating smaller participant overlap (yellow  =  largest overlap, light blue  =  smallest overlap). Seed locations are indicated by arrows (CC, corpus callosum).
