PVALB and schizophrenia: Loss of parvalbumin interneurons in the hippocampus and prefrontal cortex has been reported in many animal models of schizophrenia, including neonatal hippocampal lesion (Cabungcal et al., 2014), maternal immune activation (Piontkewitz et al., 2012), amygdala disinhibition (Berretta et al., 2009), and MAM-E17 models (Penschuck et al., 2006; Lodge et al., 2009; Chen et al., 2014; Gill and Grace, 2014).
