Conjunctive visual search (<jats:styled-content style=\"fixed-case\">CVS<\/jats:styled-content>) is a useful tool for mapping visual function during<jats:styled-content style=\"fixed-case\">fMRI<\/jats:styled-content>because of its greater activation extent compared with high\u2010capacity parallel search processes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Aims<\/jats:title><jats:p>The purpose of this work was to develop and evaluate a<jats:styled-content style=\"fixed-case\">CVS<\/jats:styled-content>that was capable of generating consistent activation in the basic and higher level visual areas of the brain by using a high number of distractors as well as an optimized contrast condition.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and methods<\/jats:title><jats:p>Images from 10 healthy volunteers were analyzed and brain regions of greatest activation and deactivation were determined using a nonbiased decomposition of the results at the hemisphere, lobe, and gyrus levels.

As expected, the task demonstrated deactivation patterns commonly implicated in the default\u2010mode network. Further deactivation was noted in the posterior region of the cerebellum, most likely associated with the formation of optimal search strategy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>We believe the task will be useful in studies of visual and selective attention in the neuroscience community as well as in mapping visual function in clinical<jats:styled-content style=\"fixed-case\">fMRI<\/jats:styled-content>.<\/jats:p><\/jats:sec>","DOI":"10.1002\/brb3.213","type":"journal-article","created":{"date-parts":[[2014,1,20]],"date-time":"2014-01-20T02:22:52Z","timestamp":1390184572000},"page":"227-237","source":"Crossref","is-referenced-by-count":38,"title":["Functional<scp>MRI<\/scp>mapping of visual function and selective attention for performance assessment and presurgical planning using conjunctive visual search"],"prefix":"10.1002","volume":"4","author":[{"given":"Jason G.","family":"Parker","sequence":"first","affiliation":[{"name":"Research Institute Wright State University 4035 Colonel Glenn Highway Dayton Ohio 45435"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric J.","family":"Zalusky","sequence":"additional","affiliation":[{"name":"Imaging Science Research Kettering Health Network 3535 Southern Blvd. Boonshoft Tower 4th Floor Kettering Ohio 45458"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cemil","family":"Kirbas","sequence":"additional","affiliation":[{"name":"Research Institute Wright State University 4035 Colonel Glenn Highway Dayton Ohio 45435"},{"name":"Department of Psychiatry Wright State University 627 S.
