Fig. 2. Group differences in the seed-based FC patterns between BECTS patients and control subjects. A: Increased FC was observed with voxels in the left inferior temporal gyrus in the patient group than in the control group when using a Rolandic mask covering the bilateral inferior frontal gyri (pars triangularis and pars opercularis) and the Rolandic operculum and insula as the seed. B: Increased FC was observed with voxels in the left inferior temporal gyrus in the patient group than in the control group when using a language mask covering the bilateral inferior frontal gyri, middle and superior temporal gyri, and supramarginal gyri in addition to the left angular gyrus and left cerebellar crus I as the seed. BECTS: benign childhood epilepsy with centrotemporal spikes, FC: functional connectivity.
