Age-Related Differences in Test-Retest Reliability in Resting-State Brain Functional Connectivity
Resting-state functional MRI (rs-fMRI) has emerged as a powerful tool for investigating brain functional connectivity (FC). Research in recent years has focused on assessing the reliability of FC across younger subjects within and between scan-sessions. Test-retest reliability in resting-state functional connectivity (RSFC) has not yet been examined in older adults. In this study, we investigat...
متن کاملFunctional brain hubs and their test-retest reliability: A multiband resting-state functional MRI study
Resting-state functional MRI (R-fMRI) has emerged as a promising neuroimaging technique used to identify global hubs of the human brain functional connectome. However, most R-fMRI studies on functional hubs mainly utilize traditional R-fMRI data with relatively low sampling rates (e.g., repetition time [TR]=2 s). R-fMRI data scanned with higher sampling rates are important for the characterizat...
متن کاملTest-Retest Reliability of Graph Metrics in Functional Brain Networks: A Resting-State fNIRS Study
Recent research has demonstrated the feasibility of combining functional near-infrared spectroscopy (fNIRS) and graph theory approaches to explore the topological attributes of human brain networks. However, the test-retest (TRT) reliability of the application of graph metrics to these networks remains to be elucidated. Here, we used resting-state fNIRS and a graph-theoretical approach to syste...
متن کاملSex-by-age differences in the resting-state brain connectivity
Connectomics is a state-of-the-art framework that models brain structure and function interconnectivity as a network in order to better understand the human brain as a whole, rather than narrowly focusing on select regions-of-interest. MRI-derived connectomes can be structural, usually based on diffusion-weighted MR imaging, or functional, usually formed by examining fMRI blood-oxygen-level-dep...
متن کاملResting-State Functional Connectivity in Rat Brain
Introduction Synchronized low-frequency fluctuations in resting-state fMRI (1) have been used to investigate functional connectivity between brain areas. Recent studies demonstrate that this technique can be utilized in the study of Alzheimers disease (2), antidepressant effects (3), and default mode of brain networks (4). So far, most resting-state fMRI studies have been performed on humans...
