* Post hoc tests indicated that schizophrenia (SZ) was significantly different from bipolar disorder (BD) and healthy subjects (HS) (Tukey’s honestly significant difference test, p < 0.05). ^† Post hoc tests indicated that volumes were significantly different as follows; HS > BD > SZ (Tukey Honestly Significant Difference, p < 0.05).
