The Difference of Brain Functional Connectivity between Eyes-Closed and Eyes-Open Using Graph Theoretical Analysis
Figure 3
The distribution of difference nodes between EC and EO states in theta, alpha, and beta frequency bands (the crosstab test, ). The difference node of EC state when the degree of a node in EC state was always significantly greater than that of EO state at each cost. The difference node of EO state when the degree of a node in EO state was always significantly greater than that of EC state at each cost. The triangle represented the difference node of EC state, and the rectangle represented difference node of EO state; (a) the standard layout of brain cap; (b) six difference nodes of EC state mainly located in the frontal area in the theta band (4–7 Hz); (c) thirteen difference nodes of EC state mainly located in the bilateral posterior area in the alpha band (8–13 Hz); and (d) three difference nodes of EO located in the occipital area in the beta band (14–30 Hz).
