GM and WM activations detected using GM and WM HRFs. The first and second rows show the activation map based on canonical HRF model embedded in SPM (first row, P < 0.05, two sample t-test, FWE corrected; second row, P < 0.02, two sample t-test, uncorrected). The third row and fourth row show the activation map based on a custom regressor reconstructed by convolving incongruent stimuli with the fitted HRF for the tract Fron_L to Fron_R (third row, P < 0.05, t-test, FWE corrected; fourth row, P < 0.02, t-test, uncorrected)
