Abstract:

The application of Granger Causality in the field of neuroscience is discussed with an analysis of relevant literature.We introduce the development of Granger Causality,covering its application in time and frequency domain,and nonlinear Causality.According to the definitions of Granger causality,we point out that Granger causality only used partial information of the linear regression model,and suggest the necessity of continuous improvement of Granger causality.
