Figure 4

Graphical representation of the significant differences of degree (DEG), Strength (STR), and the directional in/out-degree (INDEG/OUTDEG) and strength (INSTR/OUTSTR) values in each ROIs for each anesthesia period and EEG bands. Note: frontal area showed an increase in the in indexes in the alpha bands during the induction revealing different statistical differences between some periods whereas the statistically significant comparisons in the out indexes were highlighted in the beta band in the parietal area. *p < 0.05; **p < 0.01.
