Syntax component. Syntactic performance correlated with tissue integrity and activity in a left frontotemporal network. A, Surface view showing tissue integrity (TI) in LIFG (green) activity to AP in LIFG and LSTG (red) and activity to NP in LpSTG/MTG (blue). Central legend shows colors of the feature images and their overlap in A and B. B, sagittal sections (at the indicated MNI x-coordinate) showing tissue integrity (green) in white matter in the superior longitudinal and arcuate fasciculi, extending from LIFG to the planum temporale. All effects shown at voxel-level p < 0.001 (z > 3.09) and cluster size > 1.27 cm 3 (approximately p < 0.05 corrected). C, Higher loading values from the syntax component correlated with larger WPE AP (red) but not for WPE NP (blue). D, Higher loading values correlated with fewer reverse role errors on sentence–picture matching (RR, red) but not with lexical errors (Lex, blue). *p < 0.05; **p < 0.01; ***p < 0.001; n.s., not significant; a.u., arbitrary units.
