Grand average waveforms elicited by correctly classified match objects and by correctly classified nonmatch objects from −100 milliseconds to +1000 milliseconds in (a) the normal control (NC) group, (b) the amnestic mild cognitive impairment (aMCI) group, and (c) the Alzheimer’s disease (AD) group. Electrode sites are indicated by the inserted montage (F, C, and P stand for frontal, central, and parietal regions on the scalp, respectively). Positive voltages are plotted upward
