Note: Text in bold indicate behavioral regressors of interest; text in italics indicate neural contrasts. 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; DLPFC = Dorsolateral Prefrontal Cortex; OFC = Orbitofrontal Cortex; IFG = Inferior Frontal Gyrus; dACC = Dorsal Anterior Cingulate Cortex.
