We aimed to characterize resting-state EEG microstate dynamics in a clinically recruited adolescent NSSI sample and to examine state-dependent changes following acute social exclusion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Resting-state EEG was recorded in hospitalized, medicated adolescents with NSSI and in healthy controls (HCs). An NSSI subgroup then completed EEG assessments before and after either Cyberball-induced social exclusion or a non-stress control condition. Microstate parameters and transition probabilities were analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>After multiple-comparison correction, the core baseline finding was robustly reduced microstate A duration in the NSSI group relative to HCs. In uncorrected exploratory analyses, additional differences included shorter durations of microstates B and F, higher occurrence of microstate D, and increased F\u2192D transition probability. A multivariate pattern analysis suggested group-related information but must be interpreted cautiously given the modest sample size. Within the NSSI group, the exclusion group showed reduced microstate A expression and increased microstate D expression relative to the non-stress subgroup, with a broader transition shift toward microstate D. Several interaction effects survived correction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In this medicated inpatient sample, resting-state microstate dynamics differed from HCs, most robustly in reduced microstate A duration, and reorganized after social exclusion. Specificity to NSSI remains uncertain given the absence of an MDD-only clinical-control group and healthy Cyberball comparison. These preliminary findings require replication in larger studies including medication-naive MDD-only, MDD+NSSI, and HC groups.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fpsyt.2026.1853860","type":"journal-article","created":{"date-parts":[[2026,7,16]],"date-time":"2026-07-16T05:39:31Z","timestamp":1784180371000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Altered EEG microstate dynamics in adolescents with non-suicidal self-injury at rest and following acute social exclusion"],"prefix":"10.3389","volume":"17","author":[{"given":"Congcong","family":"Liu","sequence":"first","affiliation":[{"name":"Department of Psychology, Henan Medical University","place":["Xinxiang, Henan, China"]},{"name":"Institute of Brain and Psychological Sciences, Sichuan Normal University","place":["Chengdu, Sichuan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yajing","family":"Si","sequence":"additional","affiliation":[{"name":"Department of Psychology, Henan Medical University","place":["Xinxiang, Henan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yining","family":"Kou","sequence":"additional","affiliation":[{"name":"School of Education, Shanghai Normal University","place":["Shanghai, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huili","family":"Xing","sequence":"additional","affiliation":[{"name":"Department of Psychology, Hangzhou Normal University","place":["Hangzhou, Zhejiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Psychology, Henan Medical University","place":["Xinxiang, Henan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bin","family":"Shi","sequence":"additional","affiliation":[{"name":"Department of Psychology, Henan Medical University","place":["Xinxiang, Henan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liju","family":"Qian","sequence":"additional","affiliation":[{"name":"Shandong Daizhuang Hospital","place":["Jining, Shandong, China"]},{"name":"Jining Key Laboratory of Neuromodulation","place":["Jining, Shandong, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kun","family":"Li","sequence":"additional","affiliation":[{"name":"Shandong Daizhuang Hospital","place":["Jining, Shandong, China"]},{"name":"Jining Key Laboratory of Neuromodulation","place":["Jining, Shandong, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meng","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Psychology, Henan Medical University","place":["Xinxiang, Henan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,7,16]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1016\/s0140-6736(24)01121-8","article-title":"The lancet commission on self-harm","volume":"404","author":"Moran","year":"2024","journal-title":"Lancet (London England)"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jad.2017.09.051","article-title":"Prevalence of and risk factors for non-suicidal self-injury in rural China: Results from a nationwide survey in China","volume":"226","author":"Tang","year":"2018","journal-title":"J Affect Disord"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1016\/j.jad.2013.09.031","article-title":"Depressed adolescents as young adults -
