BDNF and schizophrenia: Namely, post-mortem studies in schizophrenia patients quite consistently report decreased BDNF expression in PFC (even more often than in the hippocampus, for review see Reinhart et al., 2015) and thus apparently differ from studies in post-weaning isolation-reared rats, considered as a model for schizophrenia (Powell, 2010; Jones et al., 2011).
