Abbreviations: L = left, R = right, HC = Healthy Control subjects, S-DUP = short duration of untreated psychosis, L-DUP =  long duration of untreated psychosis.

^a All effects survived a voxel-wise statistical threshold using ANCOVA controlling for gender, age and years of education (p<0.01, AlphaSim corrected).

^b All effects survived a voxel-wise statistical threshold using post-hoc test (p<0.01, AlphaSim corrected).

^c All effects survived a voxel-wise statistical threshold using post-hoc test (p<0.05, FDR corrected).

^d These peaks belong to the same cluster.
