Table 3. Brain Regions Showing a Significanta Correlation between fALFF and Symptom Severity within the Clinical High Risk for Psychosis (CHR) Group.
| SOPS symptom rating | Cluster anatomy | FWE cluster-corrected p-value | Cluster size (in 3 mm3 voxels) | Peak MNI coordinate (x, y, z) |
|---|---|---|---|---|
| Negative correlation: higher LFO activity associated with lower symptom severity | ||||
| Unusual thought content/delusional ideas | Bilateral superior parietal lobule/precuneus BA: 7, 31 | p=0.01 | 153 | 6, −55, 37 |
| Unusual thought content/delusional ideas | Left temporoparietal junction, extending to occipital cortex BA: 7, 19, 39 | p=0.001 | 234 | −39, −76, 31 |
| Positive correlation: higher LFO activity associated with greater symptom severity | ||||
| Negative symptom average | Left inferior prefrontal cortex BA: 47 | p=0.007 | 170 | −39, 44, 19 |
| Disorganized symptom average | Left inferior frontal and anterior insular cortex BA: 13, 46, 47 | p=0.002 | 212 | −36, 32, 22 |
Abbreviation: BA, Brodmann area.
Cluster-corrected p-values are familywise error (FWE) corrected and based on a cluster-defining height threshold of p<0.005.
