Latency of the 1st peak of activity in ms for the electrodes Oz, POz, O1, O2, PO7, PO8, PO3, PO4, P7, P8, P5 and P6. The latency increases with increasing distance from the central recording sites. Oz and POz are at the mid-line, their “relative distance” is coded (0). P7, P5, P6 and P8 are the furthest, their “relative distance” is coded (3).
