CALB2 and schizophrenia: No significant differences were observed in the number of calretinin-immunoreactive neurons in the lateral (AFF vs. CTR, P = 0.48; SZ vs. CTR, P = 0.18; SZ vs. AFF, P = 0.78), medial (pars fimbrialis and pars intermedia; AFF vs. CTR, P = 1.00; SZ vs. CTR, P = 0.76; SZ vs. AFF, P = 0.88), and dorsal septal nuclei (AFF vs. CTR, P = 0.24; SZ vs. CTR, P = 0.69; SZ vs. AFF, P = 0.78) among patients with schizophrenia, patients with affective disorders and healthy control subjects (see Figures 2A, 3A–E; Table 2).
