Lower white matter integrity is associated with poor cognitive control, a characteristic of schizophrenia that can be measured using antisaccade tasks. Although the functional neural correlates of poor antisaccade performance have been well documented, fewer studies have investigated the extent to which white matter fibers connecting the functional nodes of this network contribute to antisaccade performance. The aim of the present study was to assess the white matter structural integrity of fibers connecting two functional nodes (putamen and medial frontal eye fields) of the saccadic eye movement network implicated in poor antisaccade performance in schizophrenia. To evaluate white matter integrity, DTI was acquired on subjects with schizophrenia and two comparison groups: (a) behaviorally matched healthy comparison subjects with low levels of cognitive control (LCC group), and (b) healthy subjects with high levels of cognitive control (HCC group). White matter fibers were tracked between functional regions of interest generated from antisaccade fMRI activation maps, and measures of diffusivity were quantified. The results demonstrated lower white matter integrity in the schizophrenia group than in the HCC group, but not the LCC group who showed similarly poor cognitive control performance. Overall, the results suggest that these alterations are not specific to the disease process of schizophrenia, but may rather be a function of uncontrolled cognitive factors that are concomitant with the disease but also observed in some healthy people.<\/jats:p>","DOI":"10.1111\/psyp.12969","type":"journal-article","created":{"date-parts":[[2017,8,24]],"date-time":"2017-08-24T04:58:02Z","timestamp":1503550682000},"page":"1967-1977","source":"Crossref","is-referenced-by-count":4,"title":["White matter fiber integrity of the saccadic eye movement network differs between schizophrenia and healthy groups"],"prefix":"10.1111","volume":"54","author":[{"given":"David J.","family":"Schaeffer","sequence":"first","affiliation":[{"name":"Department of Neuroscience University of Georgia Athens Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amanda L.","family":"Rodrigue","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Georgia Athens Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Courtney R.","family":"Burton","sequence":"additional","affiliation":[{"name":"Department of Neuroscience University of Georgia Athens Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jordan E.","family":"Pierce","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Georgia Athens Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Megan N.","family":"Murphy","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Georgia Athens Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brett A.","family":"Clementz","sequence":"additional","affiliation":[{"name":"Department of Neuroscience University of Georgia Athens Georgia USA"},{"name":"Department of Psychology University of Georgia Athens Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jennifer E.","family":"McDowell","sequence":"additional","affiliation":[{"name":"Department of Neuroscience University of Georgia Athens Georgia USA"},{"name":"Department of Psychology University of Georgia Athens Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,8,23]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-8986.2011.01306.x"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0006-8993(71)90100-4"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/1522-2594(200010)44:4<625::AID-MRM17>3.0.CO;2-O"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.biopsych.2005.11.014"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1152\/jn.2000.84.3.1645"},{"key":"e_1_2_6_7_1","doi-asserted-by":"crossref","first-page":"1200","DOI":"10.1176\/ajp.156.8.1200","article-title":"Change in basal ganglia volume over 2 years in patients with schizophrenia: Typical versus atypical neuroleptics","volume":"156","author":"Corson P.
