Figure 4

Distributions of the differences of integral energy ratios in the high frequency range to the low frequency range, \({\langle {\upvarepsilon }_{H}/L\rangle }_{\mathrm{AW},\mathrm{ AS},\mathrm{ QS}}\), between the right and left hemispheres, RH and LH: (a) diagrams for AW state; (b) diagrams for QS state; (c) diagrams for AS state. The localization of EEG channels on the scalp for each hemisphere is shown above. Red color indicates estimates for group II (EEG monitoring event GA34–37^10d), green and blue colors code the estimates of the first and second monitoring events in group I, GA38–41^8h and GA38–41^10d, respectively. Gray color shows the difference range [− 0.5; 0.5], corresponding to minor activity differences between the right and left hemispheres. The diagrams depict the following statistical characteristics of numerical indicators: the first and the third quartiles (25–75%, inside the box), the median and the mean (transverse line and point inside the box, respectively), 1.5 interquartile ranges (shown by whiskers), and outliers represented by asterisks.
