Functional magnetic resonance imaging meta\u2010analyses and patient work have highlighted that frontoparietal regions, lateralized to the right hemisphere, are critical for sustained attention, though recent work implicates a broader expanse of brain regions. The current study sought to determine if and where variation in cortical thickness is significantly associated with sustained attention performance. Sustained attention was measured using the gradual onset continuous performance task and the Test of Variables of Attention in 125 adult Veteran participants after acquiring two high\u2010resolution structural MRI scans. Whole\u2010brain vertex\u2010wise analyses of the cortex demonstrated that better sustained attention was associated with increased thickness in visual, somatomotor, frontal, and parietal cortices, especially in the right hemisphere. Network\u2010based analyses revealed relationships between sustained attention and cortical thickness in the dorsal attention, ventral attention, somatomotor, and visual networks. These results indicate cortical thickness in multiple regions and networks is associated with sustained attention, and add to the growing knowledge of how structural MRI can help explain individual differences in cognition.<\/jats:p>","DOI":"10.1002\/hbm.24594","type":"journal-article","created":{"date-parts":[[2019,4,13]],"date-time":"2019-04-13T08:37:21Z","timestamp":1555144641000},"page":"3243-3253","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Individual differences in sustained attention are associated with cortical thickness"],"prefix":"10.1002","volume":"40","author":[{"given":"Alex","family":"Mitko","sequence":"first","affiliation":[{"name":"Translational Research Center for TBI and Stress Disorders (TRACTS), VA RR&amp;D TBI National Research Center VA Boston Healthcare System  Boston Massachusetts"},{"name":"Neuroimaging Research for Veterans (NeRVe) Center VA Boston Healthcare System  Boston Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Rothlein","sequence":"additional","affiliation":[{"name":"Translational Research Center for TBI and Stress Disorders (TRACTS), VA RR&amp;D TBI National Research Center VA Boston Healthcare System  Boston Massachusetts"},{"name":"Neuroimaging Research for Veterans (NeRVe) Center VA Boston Healthcare System  Boston Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Victoria","family":"Poole","sequence":"additional","affiliation":[{"name":"Neuroimaging Research for Veterans (NeRVe) Center VA Boston Healthcare System  Boston Massachusetts"},{"name":"Institute for Aging Research Hebrew SeniorLife  Boston Massachusetts"},{"name":"Beth Israel Deaconess Medical Center, Department of Medicine, Harvard Medical School  Boston Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meghan","family":"Robinson","sequence":"additional","affiliation":[{"name":"Translational Research Center for TBI and Stress Disorders (TRACTS), VA RR&amp;D TBI National Research Center VA Boston Healthcare System  Boston Massachusetts"},{"name":"Neuroimaging Research for Veterans (NeRVe) Center VA Boston Healthcare System  Boston Massachusetts"},{"name":"Geriatric Research Education and Clinical Center (GRECC) Boston Division VA Healthcare System  Boston Massachusetts"},{"name":"Department of Neurology Boston University School of Medicine  Boston Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Regina","family":"McGlinchey","sequence":"additional","affiliation":[{"name":"Translational Research Center for TBI and Stress Disorders (TRACTS), VA RR&amp;D TBI National Research Center VA Boston Healthcare System  Boston Massachusetts"},{"name":"Neuroimaging Research for Veterans (NeRVe) Center VA Boston Healthcare System  Boston Massachusetts"},{"name":"Geriatric Research Education and Clinical Center (GRECC) Boston Division VA Healthcare System  Boston Massachusetts"},{"name":"Department of Psychiatry Harvard Medical School  Boston Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph","family":"DeGutis","sequence":"additional","affiliation":[{"name":"Translational Research Center for TBI and Stress Disorders (TRACTS), VA RR&amp;D TBI National Research Center VA Boston Healthcare System  Boston Massachusetts"},{"name":"Geriatric Research Education and Clinical Center (GRECC) Boston Division VA Healthcare System  Boston Massachusetts"},{"name":"Department of Psychiatry Harvard Medical School  Boston Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Salat","sequence":"additional","affiliation":[{"name":"Translational Research Center for TBI and Stress Disorders (TRACTS), VA RR&amp;D TBI National Research Center VA Boston Healthcare System  Boston Massachusetts"},{"name":"Neuroimaging Research for Veterans (NeRVe) Center VA Boston Healthcare System  Boston Massachusetts"},{"name":"Athinoula A.
