“…It has been used to address control of the default-mode network [35,36] and the changing influences between networks with respect to age [37]. Nonetheless, due in part to temporal blurring induced by the hemodynamic response, the potential utility of effective connectivity to resting-state fMRI data, without experimental manipulation, remains a source of debate (see the section Correlation and Causality in [13]) and methodological innovation (e.g., [38]). The rest of the current review, however, will focus on methods for the analysis of functional connectivity.…”

“…An alternative would be to expand the model with terms allowing connectivity to change with context, as is done with dynamic causal modeling [6]. The assumption of stationarity may be relaxed, allowing the estimation of time-varying connectivity, using reasonable parameterizations [59], methods that require only local stationarity [60], adaptive MAR models [42] or other means to permit time variation of the model parameters [61]. …”

“…1 There are several applications for Granger causality analysis in different fields, such as: economics, 5,6 bioinformatics, 7,8 geophysics, 9,10 and neuroscience. [11][12][13] With fMRI data, recent studies have interested to derive Granger causality maps by applied Granger causality analysis among a target region of interest and all other voxels in the brain [14][15][16] and applied a conditional Granger causality analysis to evaluate the effective connectivity of resting state networks. 17,18 Two additional developments of Granger's causality idea are important.…”
