The FINDINGS of an increasing number and variety of studies have implicated the prefrontal cortex (PFC), especially the dorsolateral region, as a site of dysfunction in schizophrenia. For example, schizophrenic patients perform poorly on cognitive tasks that are subserved by neural systems involving PFC circuitry.^1,2 In addition, functional imaging studies have demonstrated reduced blood flow or metabolic activity in this region of the cerebral cortex in many schizophrenic patients.^3-7

However, despite the accumulating evidence of PFC dysfunction in schizophrenia, major challenges for research in this area continue to include (1) the identification of specific alterations of PFC circuitry in schizophrenia and (2) the development of a rational pathophysiological accounting, based on our current understanding of the structure and operation of cortical neural systems, for the relation between altered PFC circuitry and disturbed PFC function in schizophrenia.
