Webata as well. We applied Granger's statistical approach to baseline interictal data to calculate causal interactions. We hypothesized that maps of the Granger causality network (or GC maps) from interictal data might inform about the seizure network, and set out to see if “causality” in the Granger sense correlated with surgical targets.

WebGranger causality is a popular method for studying casual links between random variables ( Granger, 1969 ). Specifically, suppose that the spike train of neuron at time bin can be … WebFeb 15, 2024 · Granger causality is a commonly used method for uncovering information flow and dependencies in a time series. Here, we introduce JGC (Jacobian Granger causality), a neural network-based approach to Granger causality using the Jacobian as a measure of variable importance, and propose a variable selection procedure for …
WebFeb 16, 2024 · In these cases, using linear models may lead to inconsistent estimation of Granger causal interactions. We propose a class of … Web3. NETWORK GRANGER CAUSALITY. The limitations of identifying Granger causality using bivariate models—illustrated in the three-variable example of Figure 1—have long been known and discussed in the literature (e.g., Sims 1980). Needing to account for many variables when identifying Granger causality arises in at least two settings.
WebThe literature suggests that schizophrenia is associated with alterations in brain network connectivity. We 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 ...
