The present study aimed to explore the characteristics of static degree centrality (sDC) and dynamic degree centrality (dDC) at multiple time points after a single triggering pain in CTN patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and methods<\/jats:title><jats:p>A total of 43 CTN patients underwent resting-state function magnetic resonance imaging (rs-fMRI) before triggering pain (baseline), within 5 s after triggering pain (triggering-5 s), and 30 min after triggering pain (triggering-30 min). Voxel-based degree centrality (DC) was used to assess the alteration of functional connection at different time points.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The sDC values of the right caudate nucleus, fusiform gyrus, middle temporal gyrus, middle frontal gyrus, and orbital part were decreased in triggering-5 s and increased in triggering-30 min. The sDC value of the bilateral superior frontal gyrus were increased in triggering-5 s and decreased in triggering-30 min. The dDC value of the right lingual gyrus was gradually increased in triggering-5 s and triggering-30 min.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Both the sDC and dDC values were changed after triggering pain, and the brain regions were different between the two parameters, which supplemented each other. The brain regions which the sDC and dDC values were changing reflect the global brain function of CTN patients, and provides a basis for further exploration of the central mechanism of CTN.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fnins.2023.1109684","type":"journal-article","created":{"date-parts":[[2023,2,16]],"date-time":"2023-02-16T11:16:00Z","timestamp":1676546160000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":11,"title":["Alteration of brain network centrality in CTN patients after a single triggering pain"],"prefix":"10.3389","volume":"17","author":[{"given":"Xiuhong","family":"Ge","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luoyu","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengze","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Pan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haiqi","family":"Ye","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaofen","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandra","family":"Fan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qi","family":"Feng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Quan","family":"Du","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Wenhua","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhongxiang","family":"Ding","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2023,2,16]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"697","DOI":"10.1016\/j.neuroimage.2018.09.064","article-title":"Low-frequency direct cortical stimulation of left superior frontal gyrus enhances working memory performance.","volume":"184","author":"Alagapan","year":"2019","journal-title":"Neuroimage"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1155\/2021\/8831379","article-title":"Changes in temporal and spatial patterns of intrinsic brain activity and functional connectivity in upper-limb amputees: An fMRI study.","volume":"2021","author":"Bao","year":"2021","journal-title":"Neural Plast."},{"key":"B3","doi-asserted-by":"publisher","first-page":"784","DOI":"10.1016\/S1474-4422(20)30233-7","article-title":"Advances in diagnosis, classification, pathophysiology, and management of trigeminal neuralgia.","volume":"19","author":"Bendtsen","year":"2020","journal-title":"Lancet Neurol."},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1186\/1744-8069-3-34","article-title":"Comparison of evoked vs. spontaneous tics in a patient with trigeminal neuralgia (tic doloureux).","volume":"3","author":"Borsook","year":"2007","journal-title":"Mol.
