In this mapping study of the entire scalp area, the responses to flash (FL) and pattern reversal (PR) stimuli were studied in 34 normal subjects. The N70, P100, N135 and P180 were similar from both stimuli but with some differences in amplitude and latency, especially the variability of the latency of P100 from FL. A polarity inversion was usually seen for all components, especially at opposite ends of the scalp and a zero-potential was noted for all four components near Cz Pz. Evidence is seen that the frontal N100 is likely not the other end of a dipole involving the posterior P100. Lateral components as P120, N150 and N200 were also described. The major finding was evidence of "travelling" waves that appear to move in both the AP and PA directions throughout the scalp that eventually arrive on the posterior regions and appear as N70, P100, N135 and P180.
