Potential effects of task difficulty and syntax on cortical activations. The sentence stimuli became more complex under the SC, AS, and SS conditions in that order (Table I). According to the behavioral data (Table II), RTs also increased significantly in the same order. A: Cortical regions identified by AS–SC. The contrast of AS (Fig. 2; uncorrected P < 0.001) was used as an inclusive mask to eliminate any deactivation due to SC. The threshold was established at a Z‐score >3.1. Note that the left inferior frontal gyrus (IFG) was not significantly activated in this comparison. B: Cortical regions identified by SS–AS. The contrast of SS (Fig. 2; uncorrected P < 0.001) was used as an inclusive mask. The threshold was established at a Z‐score >3.1 (corrected P < 0.05 after SVC) with a volume of more than five voxels. Note the significant activation in the left LPMC as well as in the left dF3t and left pSTG/MTG. C: Cortical regions identified by (SS–AS) vs. (AS–SC). The threshold was established at a Z‐score >3.1 (corrected P < 0.05 after SVC). Note the significant activation in the left dF3t and left pSTG/MTG. See Table IV for the stereotactic coordinates of the activation foci.
