Resting state functional connectivity (RSFC) has been widely studied in functional magnetic resonance imaging (fMRI) and is observed by a significant temporal correlation of spontaneous low-frequency signal fluctuations (SLFs) both within and across hemispheres during rest.

Functional boundary maps identify locations where resting-state functional correlation (RSFC) patterns exhibit abrupt transitions across the cortical surface. These areal nodes were created by locating the local minima of RSFC transition as putative functional areal centers, and creating disks around the centers as areal nodes (3mm raidus).

2022年8月1日 · Resting-state functional connectivity (rsFC) measured with fMRI has been used to characterize functional brain maturation in typically and atypically developing children and adults. However, its reliability and utility for predicting development in infants and toddlers is …

2024年10月1日 · Using data from the Adolescent Brain Cognitive Development study, we identified four distinct and reproducible RSFC subtypes in children aged 9–11. Our approach involved an innovative methodological pipeline with several phases: identification, Validation, Evaluation, Prediction, and Replication.

2010年5月1日 · Building on two well-characterized RSFC networks, this work represents an initial effort in coupling resting-state measures to task-induced brain activity. Further research is needed to fully assess the potential of resting-state fMRI to complement task-based imaging research and to provide an alternative functional imaging approach for ...

2014年10月14日 · In this study, we described a method for building discrete parcels from RSFC-boundary maps. We also described a homogeneity-based metric to evaluate the quality of the parcellation, and we demonstrated that the boundary map …

2019年7月5日 · Resting-state functional magnetic resonance imaging (fMRI), a functional brain imaging examination technique, can be utilized to investigate changes of functional connectivity (FC) in the brain in a resting state. 9 This technique has a number of advantages, including precise positioning, the lack of radioactive injury, and the ability to combin...

This package contains functional boundary & parcellation maps of the cerebral cortex for 5 age cohorts that span across the adult lifespan (20–93 years). Functional boundary maps depict locations where resting-state functional correlation (RSFC) patterns exhibit abrupt transitions across the cortical surface (RSFC boundary mapping).

2012年7月2日 · While the resting state functional connectivity MRI (rsfc-MRI) reveals information about the functional organization, it also poses unique challenges for image analysis, mostly related to low signal-to-noise ratio (SNR) and the large number of voxels.

2023年6月12日 · In recent years, resting state functional connectivity (RSFC) based on neuroimaging algorithms is employed as a biomarker for evaluating the low-frequency fluctuations in brain and subsequently indicate the changes in brain function and provide evidence for “exercise-brain” effect (Zhang et al., 2012 ).
