Our results showed that lower activity in the thalamus and cuneus regions were related to suicidal ideation. The different topological organization and slightly worse local segregation of the brain network in suicidal ideation patients.
Figure 3. The NBS analysis results. A disrupted subnetwork was found in the SI group compared with the NS group (NS > SI).
Figure 1. (a) Two-sample t-test results of mfALFF between the SI and the NS groups (NS > SI, color bar represents t-score). (b) Lower mfALFF of the left cuneus and (c) higher mfALFF of the right middle temporal pole gyrus were found in the SI group compared with the NS group. (d) Two-sample t-test results of mReHo between the SI and the NS groups (NS > SI; color bar represents t-score). (e) Lower mReHo of the right cuneus and (f) higher mReHo of the left middle temporal gyrus (MTG) were found in the SI group compared with the NS group.
