Here, we investigated these networks by quantifying intrinsic functional connectivity in six individuals who had undergone surgical removal of one hemisphere. Hemispherectomy subjects and healthy controls were scanned with identical parameters on the same scanner and compared to a large normative sample (n = 1,482). Surprisingly, hemispherectomy subjects and controls all showed strong and equivalent intrahemispheric connectivity between brain regions typically assigned to the same functional network. Connectivity between parts of different networks, however, was markedly increased for almost all hemispherectomy participants and across all networks. These results support the hypothesis of a shared set of functional networks that underlie cognition and suggest that between-network interactions may characterize functional reorganization in hemispherectomy. Kliemann et al. present resting state neuroimaging data in six adults with childhood hemispherectomy, compared to controls. They find an intact functional organization into canonical networks, yet identify an increase in communication between networks—a possible characterization of functional reorganization in hemispherectomy. © 2019 The Authors | Source Title: | Cell Reports | URI: | https://scholarbank.nus.edu.sg/handle/10635/212422 | ISSN: | 2211-1247 | DOI: | 10.1016/j.celrep.2019.10.067 | Rights: | Attribution-NonCommercial-NoDerivatives 4.0 International |
