The lower row of Figure 3 shows the condition comparison (resting vs. task) of the grand average power spectra for the NACs (left plot) and LTAAs (right plot). The largest difference in the grand average power spectra across conditions is in the α band, where the reference power in the task is larger compared to the resting EO power. Within the θ band of interest, the difference is not as large, but the reference power in the task is also, on average, greater than the resting θ power.
