Current neuroimaging studies have identified grey matter volume (GMV) and resting\u2010state functional connectivity changes of pain processing regions related to neuropathic pain intensity in spinal cord injury subjects. However, the relationship between the underlying neural processes and pain extent, a complementary characteristic of neuropathic pain, is unknown. We therefore aimed to reveal the neural markers of widespread neuropathic pain in spinal cord injury subjects and hypothesized that those with greater pain extent will show higher GMV and stronger connectivity within pain related regions. Thus, 29 chronic paraplegic subjects and 25 healthy controls underwent clinical and electrophysiological examinations combined with neuroimaging. Paraplegics were demarcated based on neuropathic pain and were thoroughly matched demographically. Our findings indicate that (a) spinal cord injury subjects with neuropathic pain display stronger connectivity between prefrontal cortices and regions involved with sensory integration and multimodal processing, (b) greater neuropathic pain extent, is associated with stronger connectivity between the posterior insular cortex and thalamic sub\u2010regions which partake in the lateral pain system and (c) greater intensity of neuropathic pain is related to stronger connectivity of regions involved with multimodal integration and the affective\u2010motivational component of pain. Overall, this study provides neuroimaging evidence that the pain phenotype of spinal cord injury subjects is related to the underlying function of their resting brain.<\/jats:p>","DOI":"10.1002\/hbm.25401","type":"journal-article","created":{"date-parts":[[2021,6,16]],"date-time":"2021-06-16T10:34:35Z","timestamp":1623839675000},"page":"3733-3749","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["Supraspinal nociceptive networks in neuropathic pain after spinal cord injury"],"prefix":"10.1002","volume":"42","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6554-1735","authenticated-orcid":false,"given":"Vincent","family":"Huynh","sequence":"first","affiliation":[{"name":"Department of Neuroradiology, Clinical Neuroscience Center University Hospital Zurich &amp; University of Zurich  Zurich Switzerland"},{"name":"Spinal Cord Injury Center Balgrist University Hospital, University of Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robin","family":"L\u00fctolf","sequence":"additional","affiliation":[{"name":"Spinal Cord Injury Center Balgrist University Hospital, University of Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"Rosner","sequence":"additional","affiliation":[{"name":"Spinal Cord Injury Center Balgrist University Hospital, University of Zurich  Zurich Switzerland"},{"name":"Department of Neurology, Inselspital Bern University Hospital, University of Bern  Bern Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roger","family":"Luechinger","sequence":"additional","affiliation":[{"name":"Institute for Biomedical Engineering University and ETH Z\u00fcrich  Z\u00fcrich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Armin","family":"Curt","sequence":"additional","affiliation":[{"name":"Spinal Cord Injury Center Balgrist University Hospital, University of Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Spyridon","family":"Kollias","sequence":"additional","affiliation":[{"name":"Department of Neuroradiology, Clinical Neuroscience Center University Hospital Zurich &amp; University of Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mich\u00e8le","family":"Hubli","sequence":"additional","affiliation":[{"name":"Spinal Cord Injury Center Balgrist University Hospital, University of Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3750-1100","authenticated-orcid":false,"given":"Lars","family":"Michels","sequence":"additional","affiliation":[{"name":"Department of Neuroradiology, Clinical Neuroscience Center University Hospital Zurich &amp; University of Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,6,16]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/nrdp.2017.18"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10143-016-0807-7"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejpain.2004.11.001"},{"issue":"1","key":"e_1_2_8_5_1","doi-asserted-by":"crossref","first-page":"129","DOI":"10.1016\/j.pain.2003.12.015","article-title":"Chronic pain patients are impaired on an emotional decision\u2010making task","volume":"108","author":"Apkarian, A.
