Mean percent signal change and standard deviation in parentheses for each area showing significant main effect across SOA in functional imaging analysis. rSTG, right superior temporal gyrus; lSTG, left superior temporal gyrus; aThal, anterior thalamus; Cun, cuneus/precuneus; dACC, dorsal anterior cingulate gyrus; rVLPFC/aIns, right ventrolateral prefrontal cortex/anterior insula. P-values are marked with a less-than sign (<) if they are less than 0.001 and bold text if they are significant.
