Figure 4

Locations and source waveforms of regional sources for flanker interference (N = 21). Middle: locations of the regional sources in right lingual gyrus, left anterior cingulate gyrus, left inferior frontal gyrus, and left precentral gyrus projected onto the Talairach-transformed MNI brain. Root mean square source waveforms are shown for each regional source and condition (0–900 ms). Congruent conditions are presented in green, incongruent conditions in red. Below the source waveforms difference waves are shown in the respective colour of the regional source. The BCa bootstrap 95%-confidence interval is depicted as a grey area surrounding the difference waves. Epochs deviating from zero for > 20 ms are considered significant and coloured in green (congruent > incongruent) and red (incongruent > congruent). L = left hemisphere; R = right hemisphere.
