Fig. 7: Comparing the band power between the pretraining and posttraining resting states.

We observed no significant difference (n = 19, two-tailed paired Student’s t test, Bonferroni correction) in the spectral power changes (posttraining minus pretraining) after training. In the boxplots, dots represent individual data points, centerlines represent medians, box limits represent lower and upper quartiles, whiskers represent 1.5 times the interquartile range, and circles represent outliers.
