Note: L and R refer to left and right hemispheres; + and − refer to positive or negative activation; BA refers to Brodmann Area of peak voxel; k refers to the number of voxels in each significant cluster; t refers to peak activation level in each cluster; x, y, and z refer to MNI coordinates. Superscripts (e.g. a, b, etc.) indicate that peak voxels are part of a contiguous cluster. mPFC = Medial Prefrontal Cortex; ACC = Anterior Cingulate Cortex, MFG = Middle Frontal Gyrus, MTG = Middle Temporal Gyrus, TP = Temporal Pole, STG = Superior Temporal Sulcus, dSFG = Dorsal Superior Frontal Gyrus, IFG = Inferior Frontal Gyrus, OFC = Orbitofrontal Cortex, vmPFC = Ventromedial Prefrontal Cortex, amPFC = Anterior Medial Prefrontal Cortex, dmPFC = Dorsomedial Prefrontal Cortex, PCC = Posterior Cingulate Cortex.
