We assessed structural cerebral differences between 16 normal volunteers (NV), 16 Responder (R-SC), and 19 Non-Responder (NR-SC) schizophrenia patients. Segmented T1-weighted volumes were analyzed voxel-wise to assess local differences in gray matter volume between the three groups, using permutation tests implemented in the CamBA software. Main clusters of significant GM differences among the three groups emerged in bilateral frontal cortices, right insula and right medial temporal lobe, differences being mainly due to reduced GM volumes in NR-SC, as compared to both NV and R-SC, suggesting that differences between NV an SC may be mainly driven by NR-SC patients.
