Differential activation was for “IC – C”. IC = Incongruent and C = Congruent. Coordinates are in Talairach space in the format of (RL, AP, IS). R = Right, L = Left, A = Anterior, P = Posterior, I = Inferior and S = Superior. Voxel based p ≤ 0.005 and whole brain corrected p ≤ 0.021.

IFG = inferior frontal gyrus, MFG = middle frontal gyrus, PCG = precentral gyrus, BA = Brodmann area, IOG = inferior occipital gyrus, MOG = middle occipital gyrus, SOG = superior occipital gyrus, ITG = inferior temporal gyrus, MTG = middle temporal gyrus, IPL = inferior parietal lobule, SPL = superior parietal lobule, FG = fusiform gyrus.
