Fig. 1

a Representative images of RNAscope in situ hybridization of Hrh1 mRNA together with immunostaining of choline acetyltransferase (ChAT) in the NBM of BF for patients with schizophrenia and controls. The right panels are enlarged from the dotted box in the left panels. Left: scale bar, 30 μm. Right: scale bar, 10 μm. bf Hrh1 mRNA expression in ChAT+ or ChATcells, ChAT expression, soma size, and density of ChAT+ cells in patients with schizophrenia and controls (n = 12 for controls, n = 11 for patients with schizophrenia having positive and negative symptoms, and n = 3 for patients with schizophrenia having positive symptoms). b Quantitative analysis of Hrh1 mRNA expression in ChAT+ cells of patients with schizophrenia and controls. c Quantitative analysis of Hrh1 mRNA expression in ChAT- cells of patients with schizophrenia and controls. d Quantitative analysis of ChAT expression of ChAT+ cells in patients with schizophrenia and controls. e Quantitative analysis of soma size of ChAT+ cells in patients with schizophrenia and controls. f Quantitative analysis of density of ChAT+ cells in patients with schizophrenia and controls. All data are presented as mean ± s.e.m. and error bars represent s.e.m. *P ≤ 0.05, **P ≤ 0.01, ns nonsignificant. See also Supplementary Data 2 for further statistical information.
