Phone Number: 1-800-GRAINGER (1-800-472-4643) WebDec 1, 2013 · Granger causality mapping (GCM) is one of the most widely used methods to analyze effective connectivity in the brain. The GCM imports the concept of Granger causality (Granger, 1969, 1980) to detect the influence and its direction by exploiting temporal precedence information. In the context of the Granger causality, the fMRI time …
WebWe investigate whether large-scale Augmented Granger Causality (lsAGC) can capture such alterations using restingstate fMRI data. Our method utilizes dimension reduction combined with the augmentation of source time-series in a predictive time-series model for estimating directed causal relationships among fMRI time-series.
