Phencyclidine (PCP) was administered to male and female Lister hooded rats on postnatal days (PND) 7, 9 and 11. All PCP animals tested in adulthood (PND 53-93) showed deficits in cognitive flexibility, specifically in their ability to shift attentional set, compared to controls. This novel finding is reminiscent of the impairment observed in schizophrenia patients, and supports the validity of the early postnatal PCP regimen as a disease-like model. (c) 2008 Elsevier B.V.
