Coordinates reported in this table are significant (p < .05 FWE) after correction over small spherical volumes (SVC) or over (*) the whole brain. k represents the number of voxels when displayed at p(unc) < .001. EB = early blind; SC = sighted controls; V = voices; O = objects; SV = scrambled voices; SO = scrambled objects; L = left; R = right; G = gyrus; S = sulcus. For each region significant in the between-group contrast (left-hand table), corresponding coordinates significant in the main effect in the blind group are listed in the right-hand table. None of these regions were activated or deactivated in the sighted group, indicating that the between-group effects (blind > sighted) are driven by these regions being responsive only in the blind group. Coordinates used for SVC are as follows (in MNI space): L fusiform/inferior temporal G: [−46 −48 −16] (Gougoux et al., 2009); R fusiform G: [34 −52 −16] (Gougoux et al., 2009). Regions more responsive to voices than scrambled voices in the blind group compared with the sighted group are depicted in Figure 5.
