Participants also underwent functional magnetic resonance imaging to determine resting-state functional connectivity of the amygdala. Separate ANOVAs were used to determine group differences in self-reports on the DERS. Voxel-wise linear mixed models were performed to determine whether group influenced relationships between whole-brain functional connectivity of the amygdala and scores on the DERS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Compared with nonsmokers, smokers reported greater difficulties in emotion regulation, denoted by higher total scores on the DERS. Group differences were observed on a subscale of lack of emotional clarity, but no other subscale differences on the DERS were observed. Nonsmokers exhibited a greater negative correlation than smokers between lack of emotional clarity scores and connectivity of the amygdala with the left inferior frontal gyrus. Finally, this amygdala-to-left inferior frontal gyrus connectivity was weaker in smokers than in nonsmokers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>These findings suggest that difficulties in emotion regulation in smokers are at least partially due to lack of emotional clarity. Given the role of the inferior frontal gyrus in understanding emotional states, strengthening connectivity between the amygdala and the inferior frontal gyrus may improve emotional clarity to help smokers regulate their negative emotions, thereby improving their ability to quit smoking.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1093\/ijnp\/pyaa015","type":"journal-article","created":{"date-parts":[[2020,3,16]],"date-time":"2020-03-16T16:33:09Z","timestamp":1584376389000},"page":"409-416","source":"Crossref","is-referenced-by-count":33,"title":["Neural Basis of Smoking-Related Difficulties in Emotion Regulation"],"prefix":"10.1093","volume":"23","author":[{"given":"Paul","family":"Faulkner","sequence":"first","affiliation":[{"name":"Department of Psychology, University of Roehampton, London, United Kingdom"},{"name":"Department of Psychiatry and Biobehavioral Sciences, Semel Institute for Neuroscience and Human Behavior, Los Angeles, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andy C","family":"Dean","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Biobehavioral Sciences, Semel Institute for Neuroscience and Human Behavior, Los Angeles, California"},{"name":"The Brain Research Institute, Los Angeles, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dara G","family":"Ghahremani","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Biobehavioral Sciences, Semel Institute for Neuroscience and Human Behavior, Los Angeles, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edythe D","family":"London","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Biobehavioral Sciences, Semel Institute for Neuroscience and Human Behavior, Los Angeles, California"},{"name":"The Brain Research Institute, Los Angeles, California"},{"name":"Department of Molecular and Medical Pharmacology, University of California, Los Angeles, California"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2020,3,27]]},"reference":[{"key":"2020072901465980300_CIT0001","author":"Andersson","year":"2007"},{"key":"2020072901465980300_CIT0002","doi-asserted-by":"crossref","first-page":"29","DOI":"10.1016\/j.brat.2015.03.013","article-title":"A comparison of emotion regulation strategies in response to craving cognitions: effects on smoking behaviour, craving and affect in dependent smokers","volume":"69","author":"Beadman","year":"2015","journal-title":"Behav Res Ther"},{"key":"2020072901465980300_CIT0003","doi-asserted-by":"crossref","first-page":"284","DOI":"10.1016\/j.paid.2012.03.027","article-title":"Emotion dysregulation and anxiety in children and adolescents: gender differences","volume":"53","author":"Bender","year":"2012","journal-title":"Pers Indiv Dif"},{"key":"2020072901465980300_CIT0004","doi-asserted-by":"crossref","first-page":"155","DOI":"10.1007\/s11682-016-9511-z","article-title":"Altered resting state functional connectivity of anterior insula in young smokers","volume":"11","author":"Bi","year":"2017","journal-title":"Brain Imaging Behav"},{"key":"2020072901465980300_CIT0005","doi-asserted-by":"crossref","first-page":"1861","DOI":"10.1016\/S0140-6736(17)30867-X","article-title":"Death, disease, and tobacco","volume":"389","author":"Britton","year":"2017","journal-title":"Lancet"},{"key":"2020072901465980300_CIT0006","doi-asserted-by":"crossref","first-page":"2981","DOI":"10.1093\/cercor\/bht154","article-title":"Cognitive reappraisal of emotion: a meta-analysis of human neuroimaging studies","volume":"24","author":"Buhle","year":"2014","journal-title":"Cereb Cortex"},{"key":"2020072901465980300_CIT0007","doi-asserted-by":"crossref","first-page":"59","DOI":"10.1038\/nrn2555","article-title":"How do you feel\u2013now?
