(A) Voxel-Based Morphometry (VBM) analysis showed that the right caudate (blue area, MNI coordinates: 8, 14, −2; 81 voxels, Z = 4.74) was negatively correlated with scores of motor impulsivity, and no other results were found. (B) Psycho-Physiological Interactions (PPI) analysis suggested that in contrast to view control images, viewing BQ related images would decrease functional connectivity between right caudate and right DLPFC (red area, MNI coordinates: 54, 28, −2, 57 voxels, Z = 4.38). Both results were mapped onto a standard brain and displayed with coronal, axial, and sagittal views respectively. The numbers below represented the slice numbers. (C) The scatter plot of correlation analysis between functional connectivity (right caudate and right DLPFC) and BQDS scores in the BQD group.
