Figure 1. A whole-brain rendered image in the healthy men, showing significantly increased BOLD response when contrasting the inhibit negative and the inhibit neutral task conditions, p = .001 uncorrected with a minimum voxel extent k≥18.

The healthy men showed a network of increased activation that overlapped with previous findings (Vercammen et al., 2012, Journal of Psychiatry and Neuroscience,37(6): 379–388). We applied the statistical criterion employed previously with this paradigm (Vercammen et al., 2012, Journal of Psychiatric Research), based on a double threshold approach. A simulation script was used to determine cluster threshold (cluster_threshold_beta.m retrieved from https://www2.bc.edu/~slotnics/scripts.htm), with the following parameters: acquisition matrix (80×80), original voxel dimensions (3×3×3), number of slices (32), full width half maximum (FWHM) set to 0, resampled voxel resolution (2×2×2), mask (none), corrected p-value (.05), voxel based p-value (.001), iterations (1000).
