Granger causality fmri

WebConditional Granger causality, based on functional magnetic resonance imaging (fMRI) time series signals, is the quantification of how strongly brain activity in a certain source brain region contributes to brain activity in a target brain region, independent of the contributions of other source regions. WebJan 15, 2013 · 1. Introduction. Granger causality (GC) is a widely used method for identifying directed functional (‘causal’) connectivity in neural time series data, a key challenge for contemporary neuroscience (Bressler and Menon, 2010, Bressler and Seth, 2011, Valdes-Sosa et al., 2011).Introduced conceptually by (Wiener, 1956), and …
