Fig. 2. Regions of interest for each component of interest: For the P100/N170 components,
activity recorded under the PO7/P7/P9 (black) and PO8/P8/P10 (grey) electrodes was
merged in order to respectively represent the left/right maximal posterior activity at
these latencies. For the 300–350 ms time-window, averaged activity from the left/right
posterior regions was computed on the basis of PO7/PO3/P5/P7/O1 (black) and PO8/
PO4/P6/P8/O2 (grey) signal electrodes. Concerning the left/right maximal parietal activity,
occurring around 500–600 ms, the C1/C3/C5/CP1/CP3/CP5/P1/P3/P5 (black) and C2/C4/
C6/CP2/CP4/CP6/P2/P4/P6 (grey) was merged.
