ERPs to the standard stimuli in the Fz, Cz, Pz and Oc electrodes for the Control, RRMS and BMS groups. Notice the delayed latency of the P300 (inverted triangle) and posterior N1 (asterisk). Also notice the lack of the early frontal N1 in the BMS and RRMS group (the horizontal line indicates the time window used for statistical analysis). CON: Control group; RRMS: relapsing-remitting group; BMS: benign group
