  • Note:—SND indicates identifiable nonvocal sounds; rSEN, reverse sentences; SEN, sentences. SND, rSEN, and SEN are in the context of subjects scanned by functional MR imaging while listening to these sounds. MFG indicates middle frontal gyrus; IFG, inferior frontal gyrus; SFG, superior frontal gyrus; STS, superior temporal sulcus; MTG, middle temporal gyrus. Activation differences were considered significant at height threshold (P < .00005, random effect model uncorrected) and extent threshold (10 voxels).
