Fig. 2: EEG brain states and their distribution in DoC.

A Brain states ordered by entropy from 1 (high entropy) to 5 (low entropy). The upper triangular part of the matrices represents the centroids, or brain states, obtained from the clustering analysis. The value at row i and column j indicates the wSMI connectivity between electrode i and electrode j. The topographical plots illustrate the average of wSMI values for each electrode. B Probability distributions of brain states across all groups. Brain state 1 is predominantly observed in healthy subjects, whereas the probability of brain state 5 increases with the severity of DoC (nHealthy = 101, nMCS = 95, nUWS = 101, nAcute = 41 participants). C Dendrogram clustering displaying the Manhattan distances between brain states. D Lempel-Ziv complexity as a function of entropy for each brain state. Brain States with higher variance exhibit greater entropy and Lempel-Ziv complexity. E Weighted entropy across all groups, highlighting changes in entropy as a function of DoC severity (p-values corrected for multiple comparisons. *p < 0.05, ***p < 0.001). Error bars represent S.E.M.
