From: From wavelets to adaptive approximations: time-frequency parametrization of EEG

Figure 24

Average time-frequency maps of EEG energy density, obtained from the same data as in Figure 23. Horizontal axis-time in seconds relative to the finger movement. Vertical axes on the right of those maps indicate frequency in Hz. Energy proportional to shades of gray. Scale is arbitrary and different for each map. Curves above the maps, corresponding to figure 3, are frequency integrals of the maps below them. Vertical axes on their left sides indicate percent of change, relative to energy integrated between 3.5 and 4.5 seconds before the movement in given band. [22]
