Pharmacological models have used amphetamine, PCP or NMDA to simulate some of the symptoms. However, only two models have shown the illness as a developmental process. The neonatal ventral hippocampal lesion (NVHL) and MAM models showed marked maladaptive behavior when animals reached adulthood. Le Pen et al. (2011) and O’Donnell (2011) have described several behavioral procedures where we can find similar results with different techniques aimed at developing a dysfunctional PfC.
