SUCO and schizophrenia: Compared with the control subjects, the ALFF was significantly decreased in patients with schizophrenia on five channels [ch1 (control 8.58 ± 0.93, schizophrenia 4.77 ± 0.52, t = 3.6, p = 0.001), ch2 (control 6.00 ± 0.74, schizophrenia 3.38 ± 0.41, t = 3.0, p = 0.005), ch4 (control 8.74 ± 0.98, schizophrenia 4.37 ± 0.40, t = 4.1, p = 0.0002), ch5 (control 5.43 ± 0.64, schizophrenia 3.19 ± 0.34, t = 3.1, p = 0.004), ch6 (control 7.61 ± 1.09, schizophrenia 3.996 ± 0.43, t = 3.1, p = 0.004)], but not on the other channels (p > 0.006) (Fig. 1).
