Brain areas activated under AV, AO and VO conditions.

Brain areas activated under the AV condition in native English speakers and native Japanese speakers (voxel level p < 0.001, uncorrected; cluster level p < 0.05, corrected) and those showing greater activation in native English speakers than Japanese speakers and those vice versa (a) (voxel level p < 0.001, uncorrected). The left inferior temporal gyrus, including MT, showed greater activity in native Japanese speakers than in native English speakers. Note that activity in the right hemisphere or medial region is not shown here; instead, they are shown in Table 1. Brain areas activated by AO stimuli in native English speakers and native Japanese speakers (voxel level p < 0.001, uncorrected; cluster level p < 0.05, corrected) and those showing greater activation in native English speakers than Japanese speakers and those vice versa (b) (voxel level p < 0.001, uncorrected). There was no significant difference between groups in activity in the lateral left hemisphere. Note that activity in the right hemisphere or medial region is not shown here; instead, they are listed in Table 1. Brain areas activated by VO stimuli in native English speakers and native Japanese speakers (voxel level p < 0.001, uncorrected; cluster level p < 0.05, corrected) and those showing greater activity in native English speakers than in native Japanese speakers and those vice versa (c) (voxel level p < 0.001, uncorrected). There was no significantly greater activity in the lateral left hemisphere in native English speakers than in native Japanese speakers, except in the left posterior superior temporal gyrus. The left PPC, PFC and inferior/middle temporal gyrus including MT, as well as cerebellum showed greater activity in native Japanese speakers than in native English speakers. PPC; posterior parietal cortex. PFC; prefrontal cortex.
