Grand average ERP component traces before and after texture discrimination task (TDT) training. (a) Grand average N1 trace measured at electrodes PO7, P7, P5, P6, P8, and PO8 and (b) grand average P3 trace measured at electrodes P3, P1, Pz, P2, and P4 while participants completed 400 trials of the TDT before (orange) and after (teal) two training sessions. The vertical line at time = 0 represents the onset of the stimulus. The shaded grey segments highlight the time windows in which average ERP amplitudes were calculated. The shaded ribbons around the traces illustrate the standard error of the mean amplitude values. Electrodes are referenced to the common average.
