Figure 6.
Source locations of grand-averaged ERPs collapsed across all conditions (congruent and incongruent stimuli with no cue, double cue, centre cue, and spatial cue) over time points of the target stimulus P3 period (480–700 ms) using CLARA. Target stimulus onset is at 0 ms. Brain activations were localized in the (a) left anterior temporal lobe, (b) medial prefrontal cortex, (c) left medial temporal lobe, (d) right medial temporal lobe, and (e) medial frontal cortex. The grand-averaged source waveforms for incongruent (red lines) and congruent (black lines) stimuli, extracted using regional sources at the foci revealed by CLARA, are shown on the right of each source. The colour bar denotes source amplitude. The shaded grey area denotes the source analysis time window.
