Frontal EEG time-frequency analysis of the outcome phase. a. Stimulus-locked time-frequency plot of frontal EEG activity in the outcome phase (outcome onset at dotted line). Black outlines symbolize clusters in reward outcomes that were significantly larger than neutral. All clusters had a false discovery rate cluster size significance of p < 0.002. b. Corresponding line plots below represent % signal change and standard error from the significant cluster identified in the time-frequency plot: delta-theta frequency for reward and neutral and for loss and neutral. C, correct; I, incorrect; Neu, neutral; Rew, reward.
