Participants underwent two rs-fMRI scans, once in rested wakefulness (RW) and once after 36 h of TSD. We used psychomotor vigilance tasks (PVT) to measure vigilant attention. The region-of-interest to region-of-interest correlation was employed to analyze the relationship within the salience network (SN) and between other networks after 36 h of TSD. Furthermore, Pearson\u2019s correlation analysis investigated the relationship between altered insular functional connectivity and PVT performance.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>After 36 h of TSD, participants showed significantly decreased vigilant attention. Additionally, TSD induced decreased functional connectivity between the visual and parietal regions, whereas, a significant increase was observed between the anterior cingulate cortex and insula. Moreover, changes in functional connectivity in the anterior cingulate cortex and insula showed a significant positive correlation with the response time to PVT.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Our results suggest that 36 h of TSD impaired vigilant visual attention, resulting in slower reaction times. The decrease in visual-parietal functional connectivity may be related to the decrease in the reception of information in the brain. Enhanced functional connectivity of the anterior cingulate cortex with the insula revealed that the brain network compensation occurs mainly in executive function.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fnins.2022.889009","type":"journal-article","created":{"date-parts":[[2022,7,26]],"date-time":"2022-07-26T13:54:44Z","timestamp":1658843684000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":29,"title":["Altered insular functional connectivity correlates to impaired vigilant attention after sleep deprivation: A resting-state functional magnetic resonance imaging study"],"prefix":"10.3389","volume":"16","author":[{"given":"Weiwei","family":"Fu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cimin","family":"Dai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Letong","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tao","family":"Song","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziyi","family":"Peng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengmeng","family":"Xu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lin","family":"Xu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuguo","family":"Tang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongcong","family":"Shao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,7,26]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"17","DOI":"10.1016\/S1474-4422(17)30410-6","article-title":"Health implications of sleep and circadian rhythm research in 2017.","volume":"17","author":"Abbott","year":"2018","journal-title":"Lancet Neurol."},{"key":"B2","doi-asserted-by":"publisher","first-page":"e0122340","DOI":"10.1371\/journal.pone.0122340","article-title":"Adaptation of sensorimotor coupling in postural control is impaired by sleep deprivation.","volume":"10","author":"Aguiar","year":"2015","journal-title":"PLoS One"},{"key":"B3","doi-asserted-by":"publisher","first-page":"550","DOI":"10.1016\/j.neuron.2010.02.005","article-title":"Functional-anatomic fractionation of the brain\u2019s default network.","volume":"65","author":"Andrews-Hanna","year":"2010","journal-title":"Neuron"},{"key":"B4","doi-asserted-by":"publisher","first-page":"169","DOI":"10.1016\/j.obhdp.2011.01.009","article-title":"Lack of sleep and unethical conduct.","volume":"115","author":"Barnes","year":"2011","journal-title":"Organ.
