In these deeper layers, there was no difference in total synaptic density (p = 0.723, unpaired t test, Table 2), mean PSD-95 intensities (p = 0.951, unpaired t test), PSD-95 normalized AMPAR (p = 0.420, unpaired t test with HBC), GluN1 (p = 0.407, unpaired t test with HBC), and GluN2B (p = 0.245, unpaired t test with HBC) intensities between control and schizophrenia subjects (Fig. S2). This evidence concerns the gene DLG4 and schizophrenia.
