Fig. 4

Comparison of evoked responses to the periodic vowels and control stimuli (non-periodic non-vowels) in the “most significant” dipole sources identified by cluster analysis. A, B The “most significant” dipole sources within STG + region (outlined with a red contour) are marked by blue dots. Color shade (light blue to dark blue) indicates significance of the differences between test and control conditions in the respective point sources. The primary auditory cortex (A1) is outlined with a white contour. C, D Averaged neural current timecourses in the “most significant” sources. E, F The difference between timecourses of current evoked by the test and control stimuli. G, H T-statistics reflecting a pointwise comparison of the response timecourses to test and control stimuli. Significant differences (p < 0.05, FDR corrected) are marked in gray. Supplementary figures S4 and S5 show the similar results for non-periodic vowels and periodic non-vowels
