Postmortem investigations and the receptor affinity profile of atypical antipsychotics have implicated the participation of serotonin(2A) receptors in the pathophysiology of schizophrenia. Most postmortem studies point toward lower cortical serotonin(2A) binding in schizophrenic patients. However, in vivo studies of serotonin(2A) binding report conflicting results, presumably because sample sizes have been small or because schizophrenic patients who were not antipsychotic-naive were included. Furthermore, the relationships between serotonin(2A) binding, psychopathology, and central neurocognitive deficits in schizophrenia are unclear.
