Fig. 3.
Group-level spectral properties of normalized power. (A) Normalized power as a function of frequency for the baseline, maintenance, and recovery periods in the frontal (top) and parietal (bottom) brain regions. The solid line represents the median value, with shading representing the interquartile range. (B) Topographical representation of the normalized power for each frequency band for the baseline, maintenance, and recovery periods (note the differences in scale bars for each frequency band).
