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

Figure 26

Bottom: first 10 of 57 EEG trials (Hjorth source derivation) recorded during a voluntary finger movement (time 0). Middle plot – average of the time-frequency distributions of energy obtained from MP parametrization. Top: the same distribution in 3 dimensions. We clearly observe e.g. splitting of the alpha activity into two differently reacting subbbands, a phenomenon elusive to the classical approach.
