Fig 4. (A) Grand average of response-locked ERPs at Cz electrode, filtered for delta activity (3hz low pass), and for theta activity (3-9hz band pass), for controls, SI-BPD and NI-BPD individuals. Correct trials are depicted in blue solid lines and error trials in red lines. Scalp distribution for theta (3–9 Hz band pass filter) error activity were calculated for the two time windows (ERN and Pe), maximum and minimum values in microvolts are -4.0 and +4.0. (B) Grand average of spectral power modulation for the error trials at Cz electrode.
