However, it is still unclear how cortical structures and functions change in well-recovered patients from subcortical infarctions in motor pathway. In order to reveal neuroplasticity underlying well-recovered stroke patients, both structural (gray matter volume, GMV) and functional reorganizations (cerebral blood flow, CBF and resting-state functional connectivity, rsFC) were investigated by using multi-modal MRI. Our results showed that well-recovered stroke patients exhibited significantly increased GMV in contralesional supplementary motor area (SMA), increased CBFs in contralesional superior frontal gyrus (SFG) and supramarginal gyrus (SMG) irrespective of GMV correction. Furthermore, our results showed increased rsFC between contralesional middle temporal gyrus (MTG) and SMG. Negative correlations between CBF increases and behavior test scores were also observed, suggesting neural mechanism underlying clinical improvement. Our results suggested that neuroplasticity after chronic stroke showed in both structural and functional levels, and correlation between CBF change and clinical test suggested possible biomarker for stroke recovery.","is_dataset_classified":null,"base_score":3.332204510175204,"endowment":3.332204510175204,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"28919535","pmcid":null,"openalex_id":"https://openalex.org/W2754604161","authors":[],"funders":[{"funder_name":"National Natural Science Foundation of China","grant_id":"81601467","title":null},{"funder_name":"National Natural Science Foundation of China","grant_id":"81671659","title":null}],"total_grants":2,"fwci":1.1372,"citation_percentile":0.76615319,"influential_citations":0,"citation_trend":[{"year":2018,"count":4},{"year":2019,"count":1},{"year":2020,"count":5},{"year":2021,"count":1},{"year":2022,"count":4},{"year":2023,"count":2},{"year":2024,"count":5},{"year":2025,"count":5}],"oa_status":"closed","license":"https://www.elsevier.com/tdm/userlicense/1.0/","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S030439401730472X?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S030439401730472X?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.neulet.2017.05.066","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/28919535","host_type":"repository"}],"fields_of_study":["Functional Brain Connectivity Studies","Advanced MRI Techniques and Applications","Advanced Neuroimaging Techniques and Applications"],"mesh_terms":["Adult","Aged","Cerebral Cortex","Cerebrovascular Circulation","Chronic Disease","Female","Humans","Magnetic Resonance Imaging","Male","Middle Aged","Neural Pathways","Neuronal Plasticity","Recovery of Function","Stroke","Gray Matter"],"keywords":["Supramarginal gyrus","Neuroplasticity","Neuroscience","Cerebral blood flow","Superior frontal gyrus","Middle frontal gyrus","Supplementary motor area","Stroke recovery","Stroke (engine)","Psychology","Precentral gyrus","Medicine","Physical medicine and rehabilitation","Cardiology","Functional magnetic resonance imaging","Magnetic resonance imaging","Radiology","Rehabilitation","fMRI","Stroke","Functional Connectivity","Gray Matter Volume"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Good health and well-being"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-12T00:30:02.064875Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
