Seed-Based Connectivity Analysis in Functional MRIFunctional MRI (fMRI) methods are presented for utilizing a magnetic resonance tomograph to map connectivity between brain areas in the resting state in real-time without the use of regression of confounding signal changes. They encompass: (a) ...

Bayesiancorrelation analysisfunctional connectivityprobabilisticresting-state fMRIOne popular method of assessing brain functional connectivity (FC) is through seed-based correlation (SCA) analysis. One drawback of this method is when the seed location is varied slightly, the FC can vary dramatically. We...
Dysfunctional resting State Functional Connectivity in PDS using seed Based analysisMethods: We studied 19 adults with PDS, and 21 HC matched for age, sex, education and hand preference. Participants with PDS were assessed employing self-report, clinical PDS diagnosis before age 8, and the ...
Although the feeling of stress is ubiquitous, the neural mechanisms underlying this affective experience remain unclear. Here, we investigate functional hippocampal connectivity throughout the brain during an acute stressor and use machine learning to de
Furthermore, based on the eigengene connectivity (KME) values, the top 50 genes in the indianred and tan2 modules were selected separately to generate the coexpression subnetworks visualized using Cytoscape_v.3.7.1 to search for putative candidates with important contributions (Fig.5C). Details of...
Functional connectivityICACognitive scoresMatricsIndependent component analysis (ICA) and seed-based analyses are widely used techniques for studying intrinsic neuronal activity in task-based or resting scans. In this work, we show there is a direct link between the two, and show that there are ...
Seed-based correlation analysis is one of the most popular methods to explore the functional connectivity in the brain. Based on the time series of a seed, i.e., small regions of interest, connectivity is computed as the correlation of time series for all other pixels in the brain....
FUNCTIONAL magnetic resonance imagingPREFRONTAL cortexTEMPORAL lobeFUSIFORM gyrusSPINACHObjective of this study was to examine changes in functional connectivity (FC) in the hippocampus among patients with high myopia (HM) compared to healthy controls (HCs) through the utilization of seed-based function...
Seed-based and functional connectivity analyses as a tool for evaluating Amyotrophic Lateral Sclerosis (ALS) progression, a pilot studyThe goal of the proposed project is to determine whether repetitive transcranial magnetic stimulation (rTMS) can reverse age-related memory impairment, normalize resting ...
