M2/M4 muscarinic receptor binding in the anterior cingulate cortex in schizophrenia and mood disorders

No differences in [3H]AF-DX 384 binding were seen between the four groups. The present results provide no evidence of M2/M4 receptor alterations in the anterior cingulate cortex in schizophrenia and affective disorders and extend the body of evidence implicating cortical M1 but not M2 involvement in the pathology and pharmacotherapy of schizophrenia.
