We next addressed whether chronic chemogenetic activation of CamKIIα-positive forebrain excitatory neurons in postnatal life recapitulates the effects of early adversity in programming changes in schizophrenia-like behavior (Girardi et al., 2014; Ellenbroek et al., 1998), and repetitive behavior (Malkova et al., 2012). Here, CAMK2A is linked to schizophrenia.
