The fALFF was significantly decreased in patients with schizophrenia on five channels [ch1 (control 2.44 ± 0.17, schizophrenia 1.56 ± 0.16, t = 3.8, p = 0.0005), ch4 (control 2.53 ± 0.15, schizophrenia 1.63 ± 0.22, t = 3.3, p = 0.002), ch5 (control 1.70 ± 0.14, schizophrenia 1.13 ± 0.12, t = 3.0, p = 0.004), ch6 (control 2.26 ± 0.24, schizophrenia 1.39 ± 0.16, t = 3.1, p = 0.004), ch9 (control 1.98 ± 0.11, schizophrenia 4.41 ± 0.15, t = 3.1, p = 0.004)], but not on the other channels (p > 0.006) (Fig. 2). Here, SUCO is linked to schizophrenia.
