Neural correlates of attentional switching dysfunction in major depressive disorder: Evidence from an event-related potential study with a dual-task paradigm

Figure 3 Grand averaged ERPs in frontal, central, and parietal locations and topographical distribution of grand averaged stimulus onset asynchrony-evoked N100, P200, P300 and late positive potential of both major depressive disorder and healthy controls groups. The stimulus onset asynchrony (SOA)-evoked N100 time window is 40-120 milliseconds (ms); the SOA-evoked P200 time window is 150-250 ms, the SOA-evoked P300 time window is 250-400 ms, the SOA-evoked late positive potential time window is 400-600 ms. SOA: Stimulus onset asynchrony; MDD: Patients with major depressive disorder; HC: Healthy controls; LPP: Late positive potential.
