Changes in DMN alpha band power (eyes open) between flight conditions. (a) Statistical comparison between conditions. The bar graph depicts the mean ± SEM of the DMN alpha band power for each flight condition (*p < 0.05, **p < 0.01, ***p < 0.001). (b–d) Brain figures in the dashed boxes represent the DMN areas with higher statistical power changes in the alpha band comparing DMN ROIs between (b) in-flight versus pre-flight conditions, (c) in-flight versus post-flight conditions, (d) post-flight versus pre-flight conditions. The color bar is displayed as a family-wise corrected significance level of q value > 3, corresponding with a minimum p value of 0.05. The q statistic value was obtained from the results of the post-hoc Tuckey test of the multiple comparison corrections. Thus, the darker blue color represents brain regions with higher statistical power. The five subjects are mentioned by the respective code letter under each bar.
