Electroencephalogram-Based Brain Connectivity Analysis in Prolonged Disorders of Consciousness

Figure 3

Bar chart of relative power comparison. (a) Area power bar chart. The power ratio of frontal area (Fp1, Fp2, F3, Fz, F4, F7, and F8), central area (C3, Cz, and C4), temporal area (T3, T4, T5, and T6), parietal area (P3, Pz, and P4), and occipital area (O1, Oz, and O2). In the DOC group, the power ratios of frontal, central, parietal, and temporal regions decreased significantly. (b) Area power bar chart. It can be seen that the proportion of power in delta and theta bands in the DOC group is significantly higher than that in the CG group, while the proportion of power in alpha and beta bands in the CG group is higher than that in the DOC group, this may be the cause of the DTABR difference. (DOC: disorder of consciousness; CG: control group).
