Figure 4

Represents the distribution of cortical activity in a time-slice from 250 to 400 ms. (a) Shows topographical maps of amplitudes for each condition (left and central map) and their arithmetic subtraction (right map). (b) Represents statistical differences (T values) between conditions. Left, positive cluster, and right, negative cluster. White dots represent sensors that showed significant differences during time-window. (c) Shows the whole time-series for both conditions (blue = VALID; black = INVALID). Grey mask represents time-slice of samples with significant results.
