Resting-state functional connectivity for monolinguals and bilinguals. a, Locations of the two seed voxels in LIFG and RIFG. b, c, Correlations between activity in LIFG and RIFG seed voxel and activity in the positive and negative brain networks across a 6 min resting state, respectively. d, e, Axial brain images showing bootstrap ratios greater than ±3. Warm-colored voxels indicate that positively correlating activity was observed in the frontal–posterior network, which was strongly represented in bilinguals with the LIFG seeds in d. Cool-colored voxels indicate negatively correlating activity in the anterior left–right network, similar for both monolinguals and bilinguals in both IFG seeds.
