Abbreviations: ACC, anterior cingulate cortex; ASD, autism spectrum disorder; dlPFC, dorso-lateral prefrontal cortex; L, left; MCC, middle cingulated cortex; MNI, Montreal Neurological Institute; mPFC, medial prefrontal cortex; MTG, medial temporal gyrus; OFG, orbito-frontal gyrus; PCG, precentral gyrus; R, right; RC, repeat–correct' trial; TD, typically developing.

Note: Statistical significance was set for the significant voxels of activation at P<0.05, corrected for multiple comparisons in the whole source–space volume for within-group comparisons (recognition effect in each group; RC vs New stimuli) and at P<0.005 uncorrected for between-group comparisons (recognition contrast (RC–New stimuli) by group, highlighted in bold).
