Brain regions with ALFF differences in ECS and HCs and in ECS cognitive subtypes.
| Brain regions | Cluster size | Peak coordinate (mm)a | Peak t-value | |||
|---|---|---|---|---|---|---|
| x | y | z | ||||
| ECS > HC | Caudate L | 98 | −9 | 9 | 0 | 5.0849 |
| Thalamus B | 54 | −9 | −6 | 9 | 4.7638 | |
| ECS < HC | MPFC B | 49 | 3 | 48 | −24 | −4.4362 |
| PCC/PCu B | 100 | 3 | −54 | 21 | −4.5327 | |
| SI > MI | PreCG L | 47 | −56 | 5 | 19 | 4.9245 |
| SI < MI | PCC/PCu L | 142 | −6 | −57 | 26 | −5.488 |
SI and MI represent the two cognitive subtypes in ECS.
Peak coordinate refers to the peak voxel location of the significant cluster in the Montreal Neurological Institute space.
ALFF, amplitude of low-frequency fluctuations; ECS, early course schizophrenia; SI, severely impaired subtype; MI, moderately impaired subtype; HC, healthy control; MPFC, medial prefrontal cortex; PCC/PCu, posterior cingulate cortex/precuneus; PreCG, precentral gyrus; L, left; B, bilateral.
