fMRI results: incongruency effects. A, Increased activation for incongruent relative to congruent trials on sagittal and coronal slices of a mean structural image created by averaging the subjects' normalized structural images. Height threshold, p < 0.001 uncorrected masked with stimulus > fixation at p < 0.001. Extent threshold, > 0 voxels. B, Parameter estimates of canonical hemodynamic response function at x = 36, y = −45, z = −15. The bar graphs represent the size of the effect in nondimensional units (corresponding to percentage whole-brain mean). V, Intact vision; v, degraded vision; A, intact audition; a, degraded audition; C, congruent; I, incongruent.
