fMRI results. (A) fMRI group activation for REG and RAND conditions, superimposed onto coronal (y = −26), sagittal (x = −55), and axial (z = 12) sections of the average structural image. The height threshold for activation was P < 0.001 (uncorrected) at the peak level, P < 0.05 (FWEc.) at the cluster level. Blue, activation for RAND; orange, activation for REG. The white arrowheads on the axial section indicate the midline of Heschl’s gyrus in each hemisphere. (B) Regions showing increased hemodynamic responses to REG sequences compared with RAND, thresholded at P < 0.001 (uncorrected, but see familywise error corrected coordinate information in Table S5). Results are shown for different axial sections on the subjects’ average structural anatomy. The color map indicates peak level significance. The contrast revealed increased hemodynamic responses to REG bilaterally in PT, STG, and planum polare (PP). Additional activation in the left inferior frontal gyrus (IFG; right IFG was also present but does not survive correction for multiple comparisons; Table S5).
