Statistical Analysis of Single-Trial Granger Causality Spectra

Figure 1

Simulations. Spectral analysis of synthetic data generated using a two-node network model with two autoregressive processes 𝑋₁ and 𝑋₂ and unidirectional coupling from 𝑋₂ to 𝑋₁. (a) shows the power spectra for 𝑋₁ and 𝑋₂, (b) shows their phase synchrony spectrum, and (c) depicts the Granger causality spectra.
