Figure 1: Number of D-neurons reduced in the striatum of post-mortem brains of patients with schizophrenia. As the number of AADC-positive neurons in the striatum reduced in the brains with longer post-mortem period to death (PMI), analysis was performed using brain samples with PMI less than 8 hours. Controls: n=5 (27-64y.o.), Schizophrenics: n=6 (51-78 y.o.) [9].
