Previous studies have revealed the abnormalities in homotopic connectivity in schizophrenia. However, the relationship of these deficits to antipsychotic treatment in schizophrenia remains unclear. This study explored the effects of antipsychotic therapy on brain homotopic connectivity and whether the homotopic connectivity of these regions might predict individual treatment response in schizophrenic patients. Methods. A total of 21 schizophrenic patients and 20 healthy controls were scanned by the resting-state functional magnetic resonance imaging. The patients received olanzapine treatment and were scanned at two time points. Voxel-mirrored homotopic connectivity (VMHC) and pattern classification techniques were applied to analyze the imaging data. Results. Schizophrenic patients presented significantly decreased VMHC in the temporal and inferior frontal gyri, medial prefrontal cortex (MPFC), and motor and low-level sensory processing regions (including the fusiform gyrus and cerebellum lobule VI) relative to healthy controls. The VMHC in the superior\/middle MPFC was significantly increased in the patients after eight weeks of treatment. Support vector regression (SVR) analyses revealed that VMHC in the superior\/middle MPFC at baseline can predict the symptomatic improvement of the positive and negative syndrome scale after eight weeks of treatment. Conclusions. This study demonstrated that olanzapine treatment may normalize decreased homotopic connectivity in the superior\/middle MPFC in schizophrenic patients. The VMHC in the superior\/middle MPFC may predict individual response for antipsychotic therapy. The findings of this study conduce to the comprehension of the therapy effects of antipsychotic medications on homotopic connectivity in schizophrenia.<\/jats:p>","DOI":"10.1155\/2021\/9954547","type":"journal-article","created":{"date-parts":[[2021,9,2]],"date-time":"2021-09-02T20:51:05Z","timestamp":1630615865000},"page":"1-11","source":"Crossref","is-referenced-by-count":14,"title":["Increased Homotopic Connectivity in the Prefrontal Cortex Modulated by Olanzapine Predicts Therapeutic Efficacy in Patients with Schizophrenia"],"prefix":"10.1155","volume":"2021","author":[{"given":"Xiaoxiao","family":"Shan","sequence":"first","affiliation":[{"name":"National Clinical Research Center for Mental Disorders and Department of Psychiatry, The Second Xiangya Hospital of Central South University, Changsha, 410011 Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rongyuan","family":"Liao","sequence":"additional","affiliation":[{"name":"The Second Affiliated Hospital of Xinxiang Medical University, Xinxiang, Henan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yangpan","family":"Ou","sequence":"additional","affiliation":[{"name":"National Clinical Research Center for Mental Disorders and Department of Psychiatry, The Second Xiangya Hospital of Central South University, Changsha, 410011 Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yudan","family":"Ding","sequence":"additional","affiliation":[{"name":"National Clinical Research Center for Mental Disorders and Department of Psychiatry, The Second Xiangya Hospital of Central South University, Changsha, 410011 Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Feng","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Radiology, Tianjin Medical University General Hospital, Tianjin 300000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jindong","family":"Chen","sequence":"additional","affiliation":[{"name":"National Clinical Research Center for Mental Disorders and Department of Psychiatry, The Second Xiangya Hospital of Central South University, Changsha, 410011 Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingping","family":"Zhao","sequence":"additional","affiliation":[{"name":"National Clinical Research Center for Mental Disorders and Department of Psychiatry, The Second Xiangya Hospital of Central South University, Changsha, 410011 Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4123-5095","authenticated-orcid":true,"given":"Yiqun","family":"He","sequence":"additional","affiliation":[{"name":"The Second Affiliated Hospital of Xinxiang Medical University, Xinxiang, Henan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1626-2465","authenticated-orcid":true,"given":"Wenbin","family":"Guo","sequence":"additional","affiliation":[{"name":"National Clinical Research Center for Mental Disorders and Department of Psychiatry, The Second Xiangya Hospital of Central South University, Changsha, 410011 Hunan, China"},{"name":"Department of Psychiatry, The Third People\u2019s Hospital of Foshan, Foshan, 528000 Guangdong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1111\/jcpp.12307"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.schres.2012.07.027"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1017\/S0033291700035674"},{"key":"4","doi-asserted-by":"crossref","first-page":"60","DOI":"10.1016\/S0304-3940(02)00032-0","article-title":"Reduced interhemispheric transmission in schizophrenia patients: evidence from event-related potentials","volume":"320","author":"T.
