Regions exhibiting a significant interaction between time (T) and condition (C) for AX relative to BX trials (panel a) and AY relative to BX trials (panel b; p < .001: red; p < .0001: yellow). Locations of the sagittal (X) and axial (Z) slices are given according to the Talairach atlas for the left (L) and right (R) hemispheres. Percent signal change (PSC) extracted across each region are plotted over the entire hemodynamic response function (HRF) for AX (green), BX (blue), and AY (red) conditions, with error bars reflecting the standard error across participants. Shaded bars indicate peak (P; dark gray) and late peak (LP; light gray) phase of the HRF. Selected regions include bilateral anterior insula/ventrolateral prefrontal cortex (aI/VLPFC; Center of Mass: 40.4, 19.2, 4.7) for the AX relative to BX contrast and the left sensorimotor cortex (SMC; Center of Mass: 47.3, −24.6, 33.8) and the left cerebellum (Cblm; Center of Mass: −23.2, −67.1, −35.2) for the AY relative to BX contrast
