GSTM1 and schizophrenia: Patients with schizophrenia exhibited significantly smaller increases in oxy-Hb than controls for 36 channels (ch1, ch2, ch8, ch11, ch12, ch14, ch18 to ch25, ch28 to ch36, ch38 to ch46, ch49 to ch52; FDR-corrected P < 0.05, corrected with 52 channels), which were predominantly distributed between the DLPFC, VLPFC, the FPC, and temporal regions (Fig. 1).
