A significant Group×Time interaction was observed in the right supramarginal gyrus, bilateral primary and secondary visual cortex, and the right parahippocampal gyrus. The FWHM and the absolute value of the AUC were calculated for both the positive HRF response and the PSU. Results did not indicate any significant group differences in whole-brain analyses after correction for multiple comparisons. In contrast, mTBI showed significantly decreased activation in the primary visual cortex (10 sec, 16 sec, 18 sec), right secondary visual cortex (12 sec, 14 sec, 16 sec, 18 sec), and supramarginal gyrus (12 sec, 14 sec) during the PSU. These regions included the right supramarginal gyrus (R SmG), bilateral primary visual cortex (B V1), secondary right (R V2) and left (L V2) visual cortex, and the right parahippocampal gyrus (R PhG).
