Electroencephalogram-Based Brain Connectivity Analysis in Prolonged Disorders of Consciousness

Figure 7

Granger’s causality matrix diagram and circos diagram. (a, b) The Granger causality of the CG group, with more directional connections. (c, d) The Granger causality of DOC group. At the same threshold, the intensity of directed connections in the DOC group decreased significantly, and the number and intensity of directed connections between hemispheres in the DOC group decreased compared with that in the CG group. (DOC: disorder of consciousness; CG: control group).
