Fig. 2: Evaluation of PLE and LZC in the sleep dataset.
From: Altered brain dynamics index levels of arousal in complete locked-in syndrome
The mean PLE (a) and LZC (c) distributions and their respective coefficients of variation (b, d) are depicted using violin plots and box plots for each of the sleep stages. A significant increase for mPLE (with a decrease for cvPLE) and a significant decrease for mLZC (with an increase for cvLZC) are observed for deeper sleep stages. Mean PSD with standard error mean (e) is represented for awake and all sleep stages, showing that the scale-free structure of the power spectrum changes in N1, N2, N3, and REM, as the relationship in power between slow and fast frequencies is altered, with a shift towards lower frequencies (except for REM, which is most similar to the light sleep stage N1 and the waking state). Source data are provided in Supplementary Data 1.
