EEG power spectra during dual-task static (0%) and dynamic (core board) test conditions in younger adults. Median values computed among younger adults for each ROI represented by a sphere centered on the cortical region, whose radius is linearly related to power spectrum magnitude of the EEG data. Such information for panels a) and b) is also coded through a color scale titled “\(\Delta\) relative spectral power”. We reported the difference (\(\Delta\)) of the power spectra between the 0.5 s-epoch post-odd stimulus and the 0.5 s-epoch pre-odd stimulus in the same postural conditions of Fig. 3. The p-values showing statistically significant differences between (a) and (b) condition are reported in (c). Each P-value < 0.05 is represented by a sphere centered on the cortical region, whose radius is linearly related to the magnitude of the EEG data, also coded using a color scale titled “P-values”.
