Comparisons of general ERPs and time-frequency representations between patients and healthy controls. (A) General ERP waveforms at Cz electrode at group level and their difference; (B) Topographies of averaged amplitude across target-locked 0-800 ms; (C) Comparison of general amplitude at Cz; (D) γ-ERS at Cz electrode; (E) Topographies of γ-ERS; (F) Comparison of γ-ERS at Cz electrode; (G) High α-band activity at the primary visual cortex (i.e., PO5, PO7, O1, PO6, PO8 and O2 electrodes); (H) Topographies of high α-band activity; (I) Comparison of High α-band activity at the primary visual cortex. *p < 0.05. PSD, power spectral density; ERS, event-related synchronization; ERPs, event-related potentials
