Effects of Pubertal Cannabinoid Administration on Attentional Set-Shifting and Dopaminergic Hyper-Responsivity in a Developmental Disruption Model of Schizophrenia

Abstract Background: Adolescent exposure to cannabinoids in vulnerable individuals is proposed to be a risk factor for psychiatric conditions later in life, particularly schizophrenia. Evidence from studies in animals has indicated that a combination of repeated pubertal cannabinoid administration with either neonatal prefrontocortical lesion, isolation rearing, or chronic NMDA receptor antagonism administration induces enhanced schizophrenia-like behavioral disruptions. The effects of adolescent exposure to CB1 receptor agonists, however, have not been tested in a developmental disruption model of schizophrenia. Methods: This
