Oscillatory source-level EEG results for conflict/executive attention. (a) The conflict attention of EEG source results was defined as ‘Executive = incongruent target—congruent target’ with fMRI as priors. The significant activation areas in group comparisons were marked as different colors (family-wise error corrected p < 0.05) (Yellow: HC > LBD or HC > AD; Blue: AD > HC or AD > LBD; Red: LBD > HC or LBD > AD). Four frequency bands were chosen for oscillation source-level analyses: theta band: 4–7 Hz, alpha band: 8–13 Hz, beta band: 14–30 Hz, gamma band: 31–100 Hz. The time window of conflict attention was target-evoked potential from 100 ms pre-stimulus to 700 ms post-stimulus. (b) The executive attention was defined as ‘Conflict = incongruent hard target—incongruent easy target’. The time window of executive attention was target-evoked potential from 100 ms pre-stimulus to 700 ms post-stimulus. The symbols for colors and frequency bands were the same as the conflict attention.
