The schizophrenia patients were associated with a significantly smaller [deoxy-Hb] decrease during the 60-sec task periods than healthy controls at 18 channels (ch18–19, ch24, ch28–29, ch31, ch33–34, ch36–40, ch42, ch45, ch48–50; FDR-corrected p: 0.0001–0.017). The gene discussed is GSTM1; the disease is schizophrenia.
