Grand-average P300 waveforms (Pz) evoked by negative words in the EST pre- and post-training of EEG BF and sham-BF. After the intervention, there was a significant decrease in the P300 latency at Pz to negative words in the EEG BF group, while no significant changes were present in the sham-BF group.
