Z-score map of functionally defined regions of interest (ROIs) for the contrast smoking cue minus neutral measured at the baseline session. ROI masks were created via voxel-wise correction at p = 0.05. Percent signal change was extracted from these ROIs for all 6 sessions for subsequent analysis. Specific details on ROIs, including voxels, coordinates, and specific z-score can be found in Additional file 1: Table S13
