WebEEG/fMRI studies of GGEs utilizing standard fMRI data analysis methods typically show symmetric changes in thalamic and cortical blood-oxygen-level-dependent (BOLD) signal related to GSWDs ( Fig. 1) [23–32]. Observed cortical changes usually include both GSWD-related activation and deactivation in multiple regions. WebNov 24, 2024 · Two common ways to examine such correlation patterns are via seed-based correlation analysis (SCA) and independent component analysis (ICA). SCA (Biswal et al., 1995) is a model-based method; …

WebDec 4, 2024 · Recently, there are several techniques developed to analyze the rs-fMRI data such as voxel based morphometry (VBM), i.e., seed based analysis, independent …
WebJan 1, 2003 · Our results suggest that a significant proportion of the variance in fMRI data is in fact deterministic. Double ICA training with different initial weight matrices is a simple and practical method to determine which components are reproducible. WebAug 8, 2014 · Multi-voxel pattern analysis (MVPA) has led to major changes in how fMRI data are analyzed and interpreted. Many studies now report both MVPA results and results from standard univariate voxel-wise analysis, often with the goal of drawing different conclusions from each.
