Prior work has established that task-based brain networks are stronger predictors of behavior than resting state networks, yet it is unclear if tasks only strengthen relationships that exist weakly at rest or if tasks also evoke unique relationships. A lack of discernment regarding how tasks and the resting state commonly and uniquely support executive functions precludes a holistic understanding of the neurobiological basis of executive functions. This project investigated differences in brain network organization and relationships with executive function ability between the resting state and two executive function tasks, a stop signal task and an emotional n-back task, using the Adolescent Brain and Cognitive Development Study dataset. Both executive function tasks evoked a more integrated network organization than the resting state, and executive function ability was related to different aspects of brain network organization during the resting state and during the tasks. Further, task-related shifts in brain network organization evoked several new relationships with executive function that were not detectable during the resting state and strengthened a relationship with executive function that existed weakly during the resting state. Overall, this study establishes a distinction between common and unique features of intrinsic and task-evoked brain function that facilitate executive function in children.<\/jats:p>","DOI":"10.1073\/pnas.2516929123","type":"journal-article","created":{"date-parts":[[2026,3,20]],"date-time":"2026-03-20T17:42:33Z","timestamp":1774028553000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":2,"title":["Task-evoked functional connectivity exhibits novel and strengthened relationships with executive function relative to the resting state"],"prefix":"10.1073","volume":"123","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0225-6320","authenticated-orcid":false,"given":"Mackenzie E.","family":"Mitchell","sequence":"first","affiliation":[{"name":"Department of Psychology and Neuroscience, University of North Carolina at Chapel Hill","place":["Chapel Hill"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric","family":"Feczko","sequence":"additional","affiliation":[{"name":"Masonic Institute for the Developing Brain, University of Minnesota","place":["Minneapolis"]},{"name":"Department of Pediatrics, University of Minnesota Medical School","place":["Minneapolis"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Damien A.","family":"Fair","sequence":"additional","affiliation":[{"name":"Masonic Institute for the Developing Brain, University of Minnesota","place":["Minneapolis"]},{"name":"Department of Pediatrics, University of Minnesota Medical School","place":["Minneapolis"]},{"name":"Institute of Child Development, University of Minnesota","place":["Minneapolis"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6016-6526","authenticated-orcid":false,"given":"Jessica R.","family":"Cohen","sequence":"additional","affiliation":[{"name":"Department of Psychology and Neuroscience, University of North Carolina at Chapel Hill","place":["Chapel Hill"]},{"name":"Carolina Institute for Developmental Disabilities, University of North Carolina at Chapel Hill","place":["Chapel Hill"]},{"name":"Biomedical Research Imaging Center, University of North Carolina at Chapel Hill","place":["Chapel Hill"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[2026,3,20]]},"reference":[{"key":"e_1_3_4_1_2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev-psych-113011-143750"},{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1006\/cogp.1999.0734"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1467-8624.2010.01499.x"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-023-42540-8"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1162\/jocn_a_01487"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1502829112"},{"key":"e_1_3_4_7_2","doi-asserted-by":"publisher","DOI":"10.1093\/cercor\/bhz150"},{"key":"e_1_3_4_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tics.2022.11.005"},{"key":"e_1_3_4_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.dcn.2019.100706"},{"key":"e_1_3_4_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuroimage.2014.09.045"},{"key":"e_1_3_4_11_2","doi-asserted-by":"publisher","DOI":"10.1002\/hbm.23219"},{"key":"e_1_3_4_12_2","doi-asserted-by":"publisher","DOI":"10.1093\/cercor\/bhu036"},{"key":"e_1_3_4_13_2","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.0511-22.2022"},{"key":"e_1_3_4_14_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0704320104"},{"key":"e_1_3_4_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuroimage.2007.08.008"},{"key":"e_1_3_4_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cobeha.2021.04.002"},{"key":"e_1_3_4_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tics.2021.09.005"},{"key":"e_1_3_4_18_2","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.2965-15.2016"},{"key":"e_1_3_4_19_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuron.2014.05.014"},{"key":"e_1_3_4_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuron.2018.03.035"},{"key":"e_1_3_4_21_2","doi-asserted-by":"publisher","DOI":"10.1098\/rstb.2013.0526"},{"key":"e_1_3_4_22_2","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.0358-16.2016"},{"key":"e_1_3_4_23_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuron.2016.09.018"},{"key":"e_1_3_4_24_2","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.1634-14.2014"},{"key":"e_1_3_4_25_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.dcn.2020.100862"},{"key":"e_1_3_4_26_2","doi-asserted-by":"crossref","unstructured":"M.
