PVALB and schizophrenia: MAM-E17 exposed rats model a wide range of neuroanatomical abnormalities associated with schizophrenia (Lodge and Grace, 2009), including reduced frontal cortical thickness, increased ventricle volume (Moore et al., 2006), and a loss of prefrontal cortical and ventral hippocampal parvalbumin-expressing (PV+) interneurons (Lodge et al., 2009).
