	Of 172,800 voxels, 66,123 voxels (38.27%) were contained in the mask, and subsequently included in cluster identification. See Table 1 for significant clusters sizes at alpha = 0.05, cluster sizes rounded up to the nearest integer. Voxel-wise p-threshold of 0.10, two clusters were identified, one at posterior cingulate cortex (PCC), the other in medial frontal cortex (mPFC; see Figure 2). The clusters identified at voxel-wise p-threshold 0.05 and 0.04 were also in posterior cingulate cortex cluster. At voxel-wise p-threshold of 0.03 a PCC and inferior frontal gyrus (IFG) region were identified. At voxel-wise p-threshold of 0.02, PCC, IFG and subgenual prefrontal cortical region (sgPFC) regions were identified (see Figure 3). At voxel-wise p-threshold of 0.01, sgPFC and PCC were identified. At voxel-wise p-threshold of 0.005, no clusters were identified, and at 0.0001, one cluster was identified in sgPFC. See ~~Table~~ 2 for characteristics of identified clusters. Clusters were found in a total of four brain regions, PCC, MPFC, IFG, and sgPFC (summary of findings in Table 3). The average t-value (4.316 per cluster) was largest for the sgPFC region (7.420) identified at voxel-wise p-thresh of 0.001, and smallest for MPFC region (2.819) at voxel-wise p-treshold of 0.10 (see Table 2). Of note, as the voxel-wise p-threshold became more conservative, the number of voxels in a cluster needed for significance decreased.

The average t-value (4.316 per cluster) was largest for the sgPFC region (7.420) identified at voxel-wise p-thresh of 0.001, and smallest for MPFC region (2.819) at voxel-wise p-treshold of 0.10 (see Table 2). Of note, as the voxel-wise p-threshold became more conservative, the number of voxels in a cluster needed for significance decreased.

	Of 172,800 voxels, 66,123 voxels (38.27%) were contained in the mask, and subsequently included in cluster identification. See Table 1 for significant clusters sizes at alpha = 0.05, cluster sizes rounded up to the nearest integer. Voxel-wise p-threshold of 0.10, two clusters were identified, one at posterior cingulate cortex (PCC), the other in medial frontal cortex (mPFC; see Figure 2). The clusters identified at voxel-wise p-threshold 0.05 and 0.04 were also in posterior cingulate cortex cluster. At voxel-wise p-threshold of 0.03 a PCC and inferior frontal gyrus (IFG) region were identified. At voxel-wise p-threshold of 0.02, PCC, IFG and subgenual prefrontal cortical region (sgPFC) regions were identified (see Figure 3). At voxel-wise p-threshold of 0.01, sgPFC and PCC were identified. At voxel-wise p-threshold of 0.005, no clusters were identified, and at 0.0001, one cluster was identified in sgPFC. See Table 2 for characteristics of identified clusters. Clusters were found in a total of four brain regions, PCC, MPFC, IFG, and sgPFC (summary of findings in Table 3). The average t-value (4.316 per cluster) was largest for the sgPFC region (7.420) identified at voxel-wise p-thresh of 0.001, and smallest for MPFC region (2.819) at voxel-wise p-treshold of 0.10 (see Table 2).
