Administration of phencyclidine (PCP) to both humans and animals models the symptoms of schizophrenia. Brain concentrations of N-acetylaspartate (NAA) are reduced in this disease, reflecting neuronal dysfunction. This study investigates the effects in rats of a chronic intermittent regime of PCP on NAA and its precursor N-acetylaspartylglutamate (NAAG) in rat frontal and temporal cortex,...
Numerous human imaging studies have revealed an absolute or relative metabolic hypofunction within the prefrontal cortex, thalamus and temporal lobes of schizophrenic patients. The former deficit correlates with cognitive deficits and negative symptoms, whereas the latter correlates with positive symptomologies. There is also general consensus that schizophrenia is associated with decreased...
