Figure 3

Time-frequency mapping of relative power changes (uncorrected) for one typical left-LPFC channel during the impulsive and non-impulsive decisions of participant 1 (a) and participant 2 (b). Yellow-to-red colors denote increased relative power (from 0.1% to 100%), while cyan-to-blue colors denote decreased relative power (from −0.1% to −100%). Green color denotes no power change.
