| Research Abstract |
Functional connectivities among cerebral cortical areas wereassessed by electroencephalography and magnetoencephalography in patients with schizophrenia. Drug-naive and first-episode patients exhibited reduced synchronizations of neural activities across global cortical areas. This reduction was most prominent betweenfrontal regions and other cortical areas. Amelioration of symptoms by antipsychotics was positively correlated with the improvement of the global synchronizations. Chronic patients, after the long-term treatments, showed increased coherences among cortical areas. Antipsychotic treatment appeared to have an effect to enhance the cortical synchronization.
