However, the factor structure of HUD trait impulsivity (motor, attentional, and nonplanning) and its neural correlates are not yet known. A total of 24 male volunteers with HUD and 16 healthy control volunteers were recruited for this cross-sectional study. The Barratt Impulsiveness Scale (BIS-11) and resting-state functional magnetic resonance imaging (rs-fMRI) were employed using the insula as a seed point in an effort to understand the association between trait impulsivity and its intrinsic factors and functional connectivity (FC) between the insula and the whole brain. The HUD group in this study exhibited higher total trait impulsivity scores, motor impulsivity, and nonplanning impulsivity than the control group. Changes in FC between the right insula and the lateral occipital cortex and the right angular gyrus were significantly positively correlated with total trait impulsivity scores, motor impulsivity, and nonplanning impulsivity, whereas changes in the FC between the left insula and the left superior frontal gyrus and left frontopolar brain region were significantly negatively correlated with trait impulsivity. Thus, the insula may serve as an important biomarker for identifying trait impulsivity and its intrinsic factor structure in patients with HUDs.<\/jats:p>","DOI":"10.3390\/brainsci13111508","type":"journal-article","created":{"date-parts":[[2023,10,25]],"date-time":"2023-10-25T09:54:08Z","timestamp":1698227648000},"page":"1508","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Insula Connectivity Abnormalities Predict Impulsivity in Chronic Heroin Use Disorder: A Cross-Sectional Resting-State fMRI Study"],"prefix":"10.3390","volume":"13","author":[{"given":"Yan","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Aviation Psychology, Air Force Medical Center, People\u2019s Liberation Army (PLA), Beijing 100142, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5426-8684","authenticated-orcid":false,"given":"Xiao","family":"Zhong","sequence":"additional","affiliation":[{"name":"School of Psychology, Beijing Sport University, Beijing 100084, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongcong","family":"Shao","sequence":"additional","affiliation":[{"name":"School of Psychology, Beijing Sport University, Beijing 100084, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingjing","family":"Gong","sequence":"additional","affiliation":[{"name":"School of Psychology, Beijing Sport University, Beijing 100084, China"},{"name":"Department of Medical Psychology, Second Medical Center, PLA General Hospital, Beijing 100853, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"180","DOI":"10.1093\/psyrad\/kkac021","article-title":"Neurobiological Mechanisms and Related Clinical Treatment of Addiction: A Review","volume":"2","author":"Fang","year":"2022","journal-title":"Psychoradiology"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"110148","DOI":"10.1016\/j.pnpbp.2020.110148","article-title":"Chronic Heroin Use Disorder and the Brain: Current Evidence and Future Implications","volume":"111","author":"Tolomeo","year":"2021","journal-title":"Prog.
