Immunohistochemistry was carried out as described in the eAppendix in the Supplement, using the avidin-biotin complex–diaminobenzidine method. Given the findings (see Results), we investigated whether ZNF804A immunoreactivity was affected by schizophrenia or rs1344706 using the sections of inferior parietal lobe (eTable 1 in the Supplement). We focused our analyses on lamina III pyramidal neurons, measuring their density, size, and staining intensity (eAppendix in the Supplement).
