Figure 6. — VEP topographies in the AM stimulus condition, the composite VEP from the summed control stimulus conditions, the SSDW and the corresponding cluster level statistics over time after the onset of S2 (t = 0 ms). Scalp voltage topographies represent values at the indicated time points. Statistical maps are averaged over an interval of ±12.5 ms around the indicated time points. (Upper Panel) upper row: scalp topographies of the VEP evoked in the AM stimulus condition (I-AM); middle row: scalp topographies of the summed VEPs in the control stimulus conditions (I-composite(AM)); bottom row: scalp topographies of the SSDW. Lower Panel: Scalp topographies of the SSDW masked by membership in a statistically significant electrode/time pair cluster as revealed by cluster level randomization analysis (P < 0.05). The nonsignificant electrode/time pairs are marked in green (n.s.). Significantly different electrode/time pair clusters are shown with their corresponding scalp voltage topography.
